One of the game announcers commented at the end that UConn had no bench scoring. Well, sort of, except 3 bench players started the game and had most of the points. The point is, as you point out, is which 6 or 7 are at your disposal. They could have gone man, but they might have also scored less than 12 second half points from chasing Houston all over the court. I'm not a big Ollie fan, don't think his teams are ever consistently focused. I think the zone decision was okay. The intensity was not. They weren't going to win anyway, but the intensity is gone.
I didn't always appreciate Calhoun's methods or temperment, but KO needs a quicker hook. When the team shot about 2 dozen more threes than he wanted the other night, JC would not have had that happen.
