If Rick calls a timeout, PC gets to not only sub, but plan for multiple attacks. Instead, Pitino allows Smith to time it perfectly...make the shot or go to OT. Zuby sets the screen, forces the switch, that leads to a 6'2 188lbs guard in Bensley Joseph trying to box out at 6'9 240 Zuby Ejifor. Joseph is in such a bad spot, that he fights like hell to get position, and falls to the ground because Zuby is an ox in the paint. That leads to the offensive rebound and the rest is history.
It worked out, why try to play revisionist history. I get if they lost but like why this way?
