I think that Perkins will be suspended though he doesn't deserve to.
I'm mad with this story because it was not intentional, and it happened on a basketball play. Pretty much like the Kobe play, the difference being that it wasn't a battle for a rebound but the setting of a screen (and that it was not intentional). Howard must have did this at least three times in this game and wasn't called for it.
But I think I'm realistic when I say that Perkins will get suspended. The NBA will want to make a statement, saying "The C's don't benefit from non suspensions", especially after the whole Rondo story and the physical plays in the Houston/LA series. And if Perkins is suspended, game 4 is a loss...
