Losing Sean Williams hurt the team incredibly (he's still in school, by the way), and, you're right, they can't run at all. They lost about 12-15 points in the transition game, sometimes giving up breaks with no one back, which is just embarassing. Good teams with speed kill them.
In other news, I hate Tyler Hansbrough. Oh man, he's so tough for playing hard when he's got a broken nose. And a frickin mask on. Wow, what a tough guy. Hockey players (who play a far more physical game) get broken noses and might wear a partial visor for a single game. Boxers break their noses once a round. Football and rugby players get broken noses and don't complain. But basketball players have to wear those masks. And then they're tough because they take all that "contact" while wearing them.
