Could not have said it better Dmopower and kenmaine, TP to both. The exact point is that Howard's elbows are not inadvertant at all. These guys are premeier athletes, they have very good control of their bodies and they genrally know where their limbs are at all times. Also, they usually know exactly where the opponent is. It's called hand-eye coordination and that athletic skill doesn't apply to just your hand, it's your whole body.
Besides that basic athletic fact, as I've argued before, if you've watched or played basketball long enough, it is so incredibly easy to tell when a play is just a good hard clean smash mouth baketball vs. when it's an intentional shot or a dirty play. It's like looking at a dog and a cat and then being asked which one is the dog and which is the cat. It's very simple.
Perkins has made plays in his career that he should clearly be suspended for. And other hard fouls he shouldn't be suspended for.
And it has nothing to do with thinking the league is against our team.
I think a pretty good guage is if my Laker friends here in LA, who absolutely despise the Celts, are admitting we are getting hosed on some of these plays and calls. Are suprised at the "non calls".
