Yeah, his usual MO on offense seems to be to bring the ball up, dribble for 5-7 seconds, then find someone--anyone--to take the ball off his hands, like it's a ticking bomb.
He ought to be in the D-League, but with the injuries to Rondo and Delonte, the big club needs him. That's actually a mixed blessing, because while I'm sure he's learning a lot, he needs to work on some things and gain confidence, and a stint in the D-League would probably work wonders for him.
Still, I've heard it said that, outside of QB, PG is the most difficult position in sports to make the transition from college to the pros. I've also heard it said that you really don't know what kind of PG you have until the 4th or 5th year in the league, so steep is the learning curve.
