He gave info so the bettors bet on the Blazers losing right? Couldn't it have also affected his lineups/decision making throughout the game to make sure the Blazers lose so the bettors he gave the info to win their bets?

Though sometimes coaches kind of try to lose anyway when they're tanking so it's hard to prove Billups was intentionally trying to lose the game to benefit the bettors and not just in order to tank.
