Kaufman-Ross memo redraws NBA betting boundaries after fraud charges

Scott Kaufman-Ross, the NBA's Executive Vice President overseeing gaming, put his name on a memo last Friday that will reshape what sportsbooks can offer when the new season opens. The directive went to authorized partners including DraftKings and FanDuel. It banned parlays combining multiple statistical unders on a single player, wagers on opening-tip winners, bets on players missing specific shots, and statistical unders on players expected to log fewer than 12 minutes.

The memo names the reason plainly: the Porter case in 2024, and the Rozier prosecution that followed.

Jontay Porter left a game against Sacramento after three minutes in March 2024. An individual connected to him had placed an $80,000 parlay on his statistical unders across six categories, with a potential payout of $1.1 million. The wager was frozen. Porter received a lifetime ban. The NBA subsequently closed the two-way contract under-bet window. The new memo closes more of the same window.

Terry Rozier's case runs along the same architecture. Prosecutors allege he disclosed information about his anticipated early departure from a March 2023 Charlotte Hornets game, enabling co-conspirators to wager more than $200,000 on his statistical unders. He played nine minutes before leaving with a foot injury. He has pleaded not guilty.

What both cases share is not merely the statistical under as an instrument. They share the specific vulnerability of a bet whose outcome a player can partially control by the act of leaving the floor. The NBA understands this. Kaufman-Ross said directly that seeing where the league had problems was one of the inputs into deciding what to restrict.

Here is where I part from the consensus framing of this story, which treats the new restrictions as a proportionate response to identified misconduct. I think they are something else: a structural acknowledgment that the line between authorized information and insider advantage in player prop markets was always thinner than the league's original sportsbook partnerships assumed. The Rozier and Porter cases did not create that vulnerability. They revealed it. The FBI probe that produced more than 30 arrests in fall 2025 did not emerge from a market that was functioning well and was then corrupted. It emerged from a market whose design contained the opportunity.

The legal standard that will govern any future enforcement action here is the one the Rozier prosecutors are already working with: 18 U.S.C. § 1343, wire fraud, which requires proof that the defendant knowingly participated in a scheme to defraud by transmitting information across wire communications for financial gain. The conspiracy charge adds the agreement element. What the NBA's memo does is not eliminate that legal exposure for players — it narrows the market surface where the exposure can be exploited, by removing the bet types most susceptible to a player's discretionary early exit.
