TOP: March 23, 2012 - Jason Smith plows into Blake Griffin. A day later, Smith is suspended 2 games for what Stu Jackson, NBA Executive Vice President Basketball Operations, deemed "excessive contact with the upper body of Griffin."
BOTTOM: May 15, 2012 - Dwyane Wade barrels into Darren Collison. Unlike Griffin, Collison never saw Wade, who shoved the Indiana PG from behind. Wade, like Smith, made no basketball play. Collison did not have the ball. Wade extended his forearm, pushing Collison underneath the basket.
Given the ruling on Smith, Wade should absolutely be suspended at least one game. Unfortunately, as we all know by now, David Stern is a crook, and the league values Dwyane and the Heat far more than Jason and the Hornets.
