One particular aspect of Sean I remember was his amazing ability to strip the ball away from whoever he was going after. I don't know if I've ever seen anyone better at it.
I appreciate you picking out one thing - because I honestly can't. I mean, honestly, not being a homer, but all-around football skills like his... I don't know if I can pick any particular thing.
Strength: check.
Speed: check.
Hands: check.
Football smarts: Generally good, and constantly improving. I guess this was the only thing that he ever faulted on occasionally, but the guy was constantly improving at this as well. He was highly emotional in the game, always wanted to score, so I guess that was sometimes to his detriment when he was young.... but the crazy thing always was, with his skill set... it was often possible he COULD score.
I have just not seen his equal. I remember a couple of times where the ball was thrown deep and he'd make his way across the field to play a part in the defense against the throw. I mean, you could simply NOT throw safely deep against the Skins if he was in deep coverage. You just couldn't. He could take away so much, almost all by himself. I don't know that I've ever seen an individual player have that much impact in a defensive strategy. Troy Polamalu comes to mind sometimes, but he doesn't have the same strength and speed - just at least in the general all-around and impact sense, I think he can play a similar role.
He was ridiculous.
