i don't think the heat's role players are as terrible as some people make em out to be. like what a few people have said here in so many words, it comes down to the system (or coach) and whether it breeds high quality shots for all the players on the court.
like for instance, people say or said San Antonio had the best bench in the league or were at least one of the deepest teams in general... but really, on an individual basis, them nyggas they got aint much more talented than what Miami got
at the start of this season, if you offered to give haslem or boris diaw, most contenders would take haslem. if you offered battier or danny green, most contenders would take battier and most nyggas would ask if green wasnt that same nygga dancin with lebron all them years ago (all they knew him for). gary neal or mario chalmers? toss up. matt bonner or james jones?? toss up... bonner may be slightly better shooting 3s (i don't know) but they the exact same type of player. dajuan blair or ronnie turiaf/joel anthony?? whatever. capt jax or mike miller? that's the captain as he's a better defender and more durable but, offensively, they're both simply just spot up shooters with basic handles who can get past their man off a pump fake after the ball is swung there way.
In other words, we saw how useless (or miami heat'ish) the Spurs bench looked the other night when their own system broke down (or when they simply couldn't make shots) and it became up to Ginobli, Parker and Duncan to try and pull a Lebron/Wade/Bosh and do everything themselves. More often than not tho, Popovich seems to have a system that gets everybody comfortable and sure of where they need to be and what they need to do. On the other hand, more often than not, you don't really get that sense with Miami and the structure they have.
