Poor choice of photo to make your point, there is very little contact there, I'm sure in the flow of the play and what occurs next may well be the contact that you are refering to.
I do believe he made this basket? And the ref's are loving that if the basket goes down we wont call it this year.
The problem with the Sixers (and it's not a new one) is that the defence played against us is alot of body contact down low (which I don't think the league should be overly cracking down on it's at an acceptable level), but when the Sixers play D it's alot of slapping and not the best use of body's. That comes from guys going for blocks alot, Cooper and Luke both go for the block time and time again, guys of that size (especially luke) need to use their body better in defense and NOT go for the block, their sheer size will change the shot enough and thus less fouls. Simon Dwight, David Stiff all suffer from the same problem.
I'm a massive fan of the block and personally find nothing better than a block of any kind BUT these guys would be much more effective if they used their body alot more.
