Fifteen thousand, nine hundred and fifty dollars in alleged net winnings is all it took to expose the most fragile point in the regulated sports betting ecosystem. According to Nevada court documents and law enforcement records obtained by ESPN, former Fresno State player Mykell Robinson is accused of manipulating his own stat line during a January 7, 2025 matchup against Colorado State while his former roommate and two ex-DraftKings sports traders allegedly hammered the under on his player props at a Las Vegas sportsbook.
Robinson logged 21 minutes that night, finishing with three points on a single three-pointer, two rebounds, and zero assists. Those box-score zeroes sit at the center of Class C felony charges carrying penalties of one to five years in prison and fines for former Fresno State and San Jose State player Steven Vasquez, along with former DraftKings traders Matthew J. Martin and Samuel Silverman, while an August arrest warrant remains active for Robinson overseas.
I look at that 21-minute stat line and see a structural math problem that sportsbooks still refuse to price properly. Player prop unders in mid-major college basketball are the softest target on the board because a single rotation player controls his own usage rate, shot volume, and rebound pursuit on every possession.
College Prop Unders Break Risk Management Models
In a standard side or total market, ten players on the floor and two coaching staffs dilute the impact of any one athlete. In an individual player prop market, the expected value math flips completely when an athlete allegedly decides to cap his own ceiling. You do not need to miss shots on purpose to cash an under when you can simply pass out of open catch-and-shoot windows, float outside the paint on defensive glass rotations, or pick up early fouls to trim your floor time down to 21 minutes.
The roster network outlined in the Nevada records shows why insider access is far more dangerous than a sharp pricing model. According to the school and the NCAA, Silverman served as a Fresno State men’s basketball team manager during the 2022-23 season, while Vasquez and Robinson lived together as Fresno State roommates in 2023-24 before Vasquez transferred to San Jose State. By 2025, Silverman and Martin were both working as sports traders in DraftKings’ Las Vegas office and living as roommates, according to the law enforcement records.
* **The Information Chain:** A former 2022-23 team manager and a 2023-24 college roommate allegedly bridged the locker room directly to a Las Vegas trading desk.
* **The On-Court Output:** Robinson recorded three points, two rebounds, and zero assists in 21 minutes against Colorado State on January 7, 2025, before the NCAA later ruled both Robinson and Vasquez ineligible following an investigation.
* **The Financial Trail:** Records obtained by ESPN indicate Martin’s under wagers on Robinson’s statistics netted $15,950 at a Las Vegas sportsbook.
When traders who understand hold percentages, bet-sizing triggers, and risk-management flags allegedly team up with the athlete on the floor, standard oddsmaking defenses collapse before tip-off.
Compliance Firewalls Only Catch the Aftermath
DraftKings sought to distance its operation from the felony filings in its statement to ESPN.
“The alleged activity at issue did not occur on DraftKings’ platform, and the individuals involved are no longer employed by the company,” a DraftKings spokesperson told ESPN in July. “We strongly condemn the alleged conduct of these former employees and remain committed to protecting the integrity of sports and sports betting.”
The company also noted that neither Martin nor Silverman had responsibilities setting college basketball odds, and that DraftKings does not operate a sportsbook in Nevada. Yet I view that corporate firewall as cold comfort when two active traders on a major operator’s payroll allegedly bet on a mid-major player prop at a Las Vegas sportsbook. The charges came after the game was played, which tells me the detection system functions as an autopsy rather than a preventative shield.
Both traders and Vasquez have pleaded not guilty to the felony charges of committing a fraudulent act in a gaming establishment and attempting or conspiring to cheat at a gambling game. “Mr. Martin looks forward to proving his innocence in a court of law and doesn’t intend to litigate the case in the press,” Martin’s attorney, Crane Pomerantz, told ESPN, while Vasquez’s counsel declined comment. Silverman, who was arrested May 5 in Las Vegas, took a similar posture through attorney Michael D. Pariente.
“We will present a vigorous defense of Mr. Silverman in a court of law based on evidence and facts — not in the court of public opinion, polluted by bias, speculation, and rumor,” Pariente told ESPN in a statement.
While the Nevada Gaming Control Board pledges in its public statement that it “will continue to aggressively investigate any activity that threatens the fairness and public confidence of regulated sports wagering,” state regulators have an obvious structural blind spot staring them in the face. My expectation is that state gaming commissions will be forced to ban individual college player props nationwide if they cannot stop a three-point, two-rebound night in the Mountain West from triggering felony warrants.
