OUR TEAM

Basketball fans, writers, analysts, podcasters, and one former player.

Every person on this page is invented. NBA Trade Mapper is a one-person project; the staff below is a running bit.


DARIUS CLEMONS

DARIUS CLEMONS

Player Personnel Consultant

6’8″ power forward out of Southeastern Louisiana. Undrafted, 2002. Signed with Golden State on the last day of training camp after their third-string power forward tore his meniscus in a preseason game against Seattle. Appeared in 14 games, shot 29% from the field. Waived in January. Spent two seasons in Atlanta as the 14th man on one of the worst rosters in modern NBA history — the 2004-05 Hawks went 13-69. His best year was 2003-04: 2.7 points, 0.8 rebounds, 3.0 minutes per game across 28 appearances. Career high of 8 points against Toronto, all in the fourth quarter, after Toronto’s starters were already in street clothes. Hawks lost by 31. Finished with 9 games in Charlotte before his expiring minimum contract was included as salary ballast in a multi-team deadline deal that routed a starting-caliber wing to the Lakers. His name appeared between two semicolons on the ESPN transaction wire. He was assigned to a Western Conference team, never reported, and was waived four days later.

VINCE TORRETTI

VINCE TORRETTI

Director of Player Evaluation

Spent nine years as an advance scout for a mid-market front office — the kind of role where you fly to Oklahoma City on a Tuesday to watch a second-round pick play 14 minutes against the Thunder, write a report no one reads until February, and fly home the next morning. He graded players on a proprietary 20-point scale he’d built over years of watching basketball in half-empty arenas. In November 2014, the front office moved a first-round pick and a 23-year-old wing for a veteran forward on an expiring deal. Torretti’s report on the wing — filed six weeks earlier — had graded him a 16 out of 20. The GM traded him anyway. The veteran left in free agency that summer. The wing made an All-Star team three years later. Torretti was let go in a restructuring the following April. He found NBA Trade Mapper in 2024 while searching the trade that ended his career. The scoring engine had graded it an F. He applied for a position the same afternoon.

EZRA KATZ

EZRA KATZ

Senior Writer

The autographed Kevin Durant rookie card sits in a UV-protective case on his desk — won at Congregation Beth Shalom’s annual trivia bowl in the spring of 2007. His father ran community relations for the Seattle SuperSonics.

Three weeks after the trivia bowl, the Sonics hired Sam Presti as general manager. Presti drafted Durant that June. The following year he drafted Russell Westbrook. The year after that, James Harden. Three future MVPs in three consecutive drafts. Katz watched it happen from Seattle — the best roster construction in the history of the league, assembled in real time, for a franchise that was already leaving. The team moved to Oklahoma City in 2008. His father’s position was eliminated.

He covers front office strategy — the draft picks nobody noticed, the two-way contracts that became rotation players, the cap decisions that built or broke a five-year window. He has an MFA from the Iowa Writers’ Workshop. His thesis was a collection of short stories about competitive swimmers. Katz does not discuss Oklahoma City.

MARA KINGSLEY

MARA KINGSLEY

NBA Analyst

Covered the Pacers beat for the Indianapolis Star-Tribune, then The Buzzer, then Hardcourt — an independent basketball publication that built a readership, went behind a paywall, and lost it. She was the last writer they kept on and the last one they let go.

Her column ran every Monday. One trade from the previous decade, re-evaluated with everything that had happened since. She called it “The Revisit.” 127 Mondays. She went back to her own column about a Pacers deal and found that her conclusion had held up but her reasoning hadn’t. She wanted to know how often that happened. It happened often.

She considers grading a trade the day it happens the height of ignorance. When two teams make a trade, they are often not trading players. They are trading time.

DION CARLISLE

DION CARLISLE

Host, The Swap

Dion Carlisle started The Swap in 2019 because nobody followed up. Every podcast reacted to trades. His show did the opposite: every trade revisited at six months, one year, and three years. He calls the three-year episode “The Verdict.”

Before the podcast, he sold medical devices in Charlotte, North Carolina. He quit to start a show about basketball trades for an audience he didn’t have yet. The audience found him. It averages 340 per episode.

He once recorded an episode about a Clippers-Thunder salary dump that eleven people downloaded and a front office cited in an internal memo. It is the only episode pinned at the top of the feed. He records from a converted closet in the East Rutherford office that the team calls “the booth” and he calls the booth.

TERRENCE “T-BONE” MASSEY

TERRENCE “T-BONE” MASSEY

Senior Trade Analyst & On-Air Commentator

Hosted The Fourth Quarter on WNJR 1430 AM out of Newark from 2011 to 2019. Four nights a week, on a signal that reached most of the Ironbound and, depending on weather, parts of Elizabeth.

He argued the Clippers should trade Chris Paul because point guards who average more than 9 assists “burn out the ball.” Paul made the All-NBA Second Team. Massey graded the season a B-minus because “the Second Team proves my point.” He predicted LeBron would go west. LeBron went to the Lakers. The Lakers missed the playoffs. Massey counted it as correct.

He found Trade Mapper after someone texted him a share card of the Butler-to-Minnesota trade. The site had it at C+ for Minnesota. Massey had given it an A on air. He emailed a rebuttal with “algorithm” misspelled in the subject line. Most of it was wrong. Buried on page two was a sentence about a gap in the scoring engine nobody on staff had flagged.

He files the Saturday column from a Dunkin’ Donuts on Ferry Street because his apartment Wi-Fi cuts out. He has a Google Doc titled “Optimum Outage Log” — fourteen timestamps, no analysis, and a single annotation that reads “they know.”

RACHEL XU

RACHEL XU

Lead Quantitative Analyst

PhD in applied mathematics from Columbia. Dissertation: supply chain disruptions in semiconductor manufacturing. She found the Win Shares formula on Wikipedia during a basketball argument with a labmate and spent three months building a scoring engine in a Jupyter notebook nobody asked for. Before Trade Mapper, two years in a Western Conference front office analytics department, where she built predictive models for trade outcomes that the GM consulted once — before a deadline deal her model flagged as a D-minus. The GM made the deal. It graded as a D-minus. She left that summer.

She built the CATV formula and wrote the statistical framework that powers every trade grade on the site. She is the only person on staff who has refused to assign a letter grade to a trade on principle. She was overruled. The letter grades get ten times the engagement. She is from Boston and enjoys iced matcha lattes with extra foam.

NATE GERSHON

NATE GERSHON

Salary Cap Analyst

Grew up in Memphis. Was working at a player agency in New York when the salary cap jumped from $70 million to $94 million in the summer of 2016. Every team had $24 million in unexpected space. Memphis gave Chandler Parsons $22 million a year. Parsons played 95 games over three seasons. Gershon read Article VII of the CBA and understood that the contract wasn’t a mistake. It was what the rules produced. The agents wanted to know which exceptions applied. They did not want to know why. He left the following spring.

He tracks win shares per dollar spent. He has identified what the staff calls the Gershon Threshold — the cap percentage above which a contract will almost never rank as efficient, no matter how good the player is. Max players are necessary. They are also, by his metric, the worst values in the league.

He has a framed printout of Article VII, Section 6 on his wall. Nobody has asked him about it. He is waiting.

TOMÁS HERRERA

Content & Social Media Director

Tomás Herrera ran social media for a sparkling water brand in Los Angeles, a tequila company that rebranded twice during his tenure, and a co-working chain that folded before his campaigns went live. He has never worked for a product he personally uses.

He came to Trade Mapper after a Verdict Flips chart went semi-viral — screenshotted, cropped, reposted four thousand times without credit. He emailed the site that night with a reformatted version. Nobody had asked him to.

His personal Instagram has been deactivated since 2021.

JAKE LAUFER

JAKE LAUFER

Staff Writer

Jake Laufer grew up in Indianapolis going to Pacers games with his father. The happiest he ever saw his dad was during the Danny Granger years — the team with Roy Hibbert, Paul George, George Hill. Laufer loved Hibbert’s verticality. Then the league went small, Hibbert became unplayable, and Paul George demanded a trade to Oklahoma City.

He traced the chain backward. In 1996, the Sonics had traded Bobby Jackson for James Cotton and a second-round pick that became Rashard Lewis. Lewis became Emir Preldzic and a trade exception, which became Kurt Thomas and a 2008 first-round pick that became Serge Ibaka. Ibaka was traded for Victor Oladipo and Domantas Sabonis, who the Thunder traded for Paul George. George was traded to the Clippers for Shai Gilgeous-Alexander. A Bobby Jackson trade in 1996 had produced SGA.

He does not watch basketball. He watches the data — the quiet transactions from decades ago that built the teams people think they’re watching now. When he finds a new chain, his dad is still the first person he calls.

JESSIE TRAN

JESSIE TRAN

Data Engineer

She maintains the data pipeline, the scraping scripts, the Supabase schema, and the daily update workflow. She is supposed to be at Virginia Tech finishing a computer science degree. That was the plan two years ago when she started as a summer intern writing import scripts. Her parents have asked about the degree three times. She has answered three times that she’s taking a gap year.

She found the parseFloat bug — a single line storing every player with exactly zero Win Shares as null, no error, no log entry, 340 rows silently wrong. She once logged into the production database at 2 a.m. because Xu’s query was returning a number that couldn’t be right. The number was right. The trade was just that bad.

On-Camera Correspondent & Creator

D1 swimmer at the University of Miami. Chosen to host Quibi’s revival of Wild On! — spring break beaches, nightlife, the format. COVID hit. Quibi crashed. The show never aired.

She covered BMX at the Tokyo Olympics, then returned with NBC for the 2024 Paris Games covering basketball. Her interview with Anthony Edwards in Le Marais — followed by a 4 a.m. video of a hotel hallway — got six million views.

The daughter of a Cuban father and a Japanese mother. A board member of Dyslexic Miami. She does not write. Everything is video. She carries the Trade Mapper database in her head and deploys CATV scores on camera without notes.

She believes every trade is ultimately about ego. There are two categories of men — those who name their first son after themselves, and those who don’t.
