For starters, that was a bummer of a break on the buzzer-beating 3-pointer. That shot probably goes in one time in 50, but it went in, and now Houston can go into the locker room with all kinds of good feelings despite the fact that they were outplayed pretty much the entire half.
Aubrey Coleman is a pretty impressive player, with a rainbow jump shot unlike any I've seen in a long time, but Maryland is in control of this game. They need to keep moving the ball and dumping it down to Jordan Williams. No one on Houston's team can match up with Williams effectively.
Greivis Vasquez played under control and got his teammates involved, and when Good Greivis shows up, Maryland is usually in pretty good shape. He can get his shot when he wants it, but getting Sean Mosley and Dino Gregory and Eric Hayes involved is helping.
This game is in Maryland's hands. They just need to make someone other than Coleman beat them. (Easier said than done, since he apparently learned how to shoot by firing over a 18-foot tall tree in his front yard.) I don't know if Houston has another player who can step up if they slow Coleman down. Especially if Maryland starts boxing out on long misses. That's helping keep Houston in the game right now, long offensive rebounds.
