It pains me to say it, but Mr. Harrison wasn't drawing double teams last season as he had previously. The Steeler D system depends on drawing doubles, otherwise, the opponent just dinks and dunks. Last year, opponents seemed content to put a RB or TE on Harrison and flip the ball to whatever spot Polamalu just left. Result: 8 - 8.
Plus the Steelers are notorious for letting young defensive players sit and watch while the vets who "know the system" handle the heavy lifting. In the new, improved, less hazardous nfl, this approach is problematic.
I think Harrison didn't get MVP in the Detroit SB at least partially because his highlight reel from that game also included him beating the snot out of an opposing player who had gone after his knees. He was landing some haymakers as the guy was down, then paused, looked around, didn't see a flag, so went back to work educating the fella. But he still has the SB record for longest pick six on his personal highlight reel.
It was always fun to watch Harrison play, especially against the Brownies. Against the Browns, he was totally hilarious (to Steeler fans). In one game, he even body slammed a drunken fan who forgot to stay in his seat.
Good bye and thank you, James. Steeler Nation will miss you.
