Bubu is pretty much the only player with the PG instinct. Allen, McGee, etc, are capable ball-handlers, but don't have the instinct.
Bubu is as Hoiberg put it "rock solid". He's not an all-conf. player, but he's not a liability either. Typically plays great defense (top 3 of our guards) is a solid ball handler and distributor, and scores enough to keep his defenders honest. He also makes good decisions about when to try to score - and is shooting at a high % because of it. Best part is, he plays HARD - don't have to worry about effort w/ him.
If he was slow on D at the end of the game, its probably because he's not used to playing 30 mins a game.
