When I ran the hypotheticals I got my math wrong (forgetting that if Michigan State made it to the final game, Ben would pick up 80 points in the semis). So, it's a simple game -- If UNC wins, then I win the SABG bracket. (Having gone 49-14) If Michigan State pulls the upset, Ben does too (40-23). But he'll deserve it for the gutsy pick.
But, since Duke lost in the round of 16, we're all winners. In a way.
