He's 6'5 and has been known to play point in garbage time! So basically, he's Courtney Lee without the defense, the shooting, the finishing at the rim, even the passing when you come to think of it.
Larry Brown and Michael Jordan aren't exactly paragons when it comes to talent evaluation. More importantly LB seems to be borderline crazy when it comes to his players, one moment he likes them more than his own children the next they're trash that needs to be traded for other players. I'd definitely take a lot at Crittenton, he'd got good size to defend and decent shooting skills. As much as everyone here likes Ish, his small size makes him a defensive liability and unlike Brooks he can't shoot to save his life.
I remember him during his stint with Lakers...now his stink with Wizards and Bobcats are unsuccessful. But look Rockets have enough PG's. End.
