The Knicks are up 2-0 with home court advantage tonight as they look to knock the Spurs down another peg. No team in NBA history has ever come back from a 3-0 series deficit, so the stakes this evening are high.
Use Polymarket promo code GRINDERS during sign-up and deposit $20 to get $50 in new player promotional funds. Trade your $50 bonus on an expert Spurs vs. Knicks prediction of under 216.5 total points (-115) for these reasons:
“The two most likely outcomes for the total are another game where the Spurs offense can’t function at all and they continue to overpress and throw up bad shots while missing the good ones, or they slow the game down, draw more free throws, and make this an ugly defensive game. Either way, that leads to an under.
