To be honest, it looked to me like their running a very similar offense to Kentuckys, which is a motion offense that they call the dribble drive offense. In that offense the ball goes into the highpost player (Willie), who then sets a screen for a guard, and hands him the ball as he passes by. The guard then drives into the lane trying to disrupt the defense. He can either go to the basket, pass the ball to an open man, or kick the ball back to Willie who then repeats the play. Obviously you can run the P&R out of that offense as well.
I hate to beat a dead horse, but this is a very very young team with some players on it that have never played in the NBA. I don't know about you, but my expectations right now are extremely low. It's going to take at least half a season before these guys get totally comfortable with each other. Of course it's frustrating to watch at times, but keep reminding yourself, it will get better. It's probably better to try and appease yourself with individual performances rather than team continuity. There are going to be some ugly moments along the way, but eventually, I think, I hope, I pray, it will become worth it.
