Anson Mount put it best when he made Rock a 1st team Playboy AA (yes, I read it in those days). Quote Anson, "The other first team defensive tackle is Rock Perdoni of Georgia Tech, the most fierce tackler we've seen in a lifetime of watching the game. Perdoni terrorized opposing quarterbacks last year … " and I can't remember the rest. Quite accurate.
Also, I think Perdoni would be as good in today's game as he was then. We saw him in another uniform a couple of years ago: Aaron McDonald from Pitt. McDonald was a bit heavier (supposedly; he didn't look any 270 to me), but had the same quick first step, the same nose for the ball, the same relentlessness, and the same ability to get under a block and shed it. The one thing that wasn't equal was the explosion on hits. Perdoni simply blew opposing O players up; that's the only way I can think of to describe it. I can remember yelling, "Have Mercy!" after a couple of them. Not, mind, that I wanted Rock to show any.
