when Pep was on, there was no one better....but, with that said, he also benefited from a great D-line. Luke on the other hand just has IT. Great instincts, tackling machine, and a high motor. But, they also play different positions. Dan Morgan would have been a better comparison.
Yes, that great defensive line of Kemo, Lewis, and Brayton (on that token, one wonders why Fox didn't play Johnson more who had 6 sacks in limited time) who helped him reach 14.5 sacks in 2008 and then 10.5 in 2009.
I know a lot of people dislike him now, and I'm not too fond of him either with how he left, but man. As of now, Peppers is quite clearly the better defensive player. Maybe Kuechly will change that in the future. But for someone to say (not saying you said it by the way, just in response to the thread) Luke in his rookie year was anywhere close to J-Pep in his prime is an idiotic statement. Lets not seriously underrate the guy because of our personal feelings towards him.
