I guess I needed clarification on what "target" means to each person. What Suh did was OUTSIDE of the rules. If Suh had wrapped Rodgers up on a sack then slide down to his calf in a continuous motion, and Rodgers hurts his calf, I wouldn't consider that "targeting." It happens within the play.
And, really, all players do that. If a player has a hurt shoulder, a defender is going to try to "target" that shoulder. Not outside the rules of the game, like Suh did. But within the rules of the game. If I know a quarterback just hurt his throwing arm, I'm going after that arm - LEGALLY. But the play comes first. If I can sack him while on the ground before he throws the ball, I'm not going to jump back to my feet and sack him by pulling his hurt arm. He may have gotten the pass off by then.
The situation dictates how I "target" him, but always within the rules and as not to hurt my team with a stupid, indefensible penalty.
