Madness wager between a pro gambler and an artificial-intelligence site will be decided by the winner of the Duke-Houston game in the Final Four. The bottom line: both pro gambler Sean Perry and the 4C's AI program have done very well over the first 60 games of the tournament.

The Houston Cougars have been to this stage before in recent history. Four years ago, in fact. That team, led by Marcus Sasser and Quentin Grimes, rode a stifling defense to the Final Four, where the inconsistent offense finally came back to bite them in a loss to eventual champs Baylor.
