That GS/BRK game had no business going under in the first place. 111 points in the 1st half, you needed an offensive meltdown to get the under.
They needed 88 points in the 2nd half to get the over. Its a 24 minute half, not a 60 second half. You want to focus on the last 60 seconds, you got a ton of good fortune in the 23 minutes prior.
