He was top notch last year! He just didn't get as much recognition because he didn't happen to fall on top of the quarterback 2 extra times.
Seriously a lot of people are only noticing him now because he has 4 sacks.
I don't see him playing much different than last year and I don't see our better run defense being because of Traylor. Our better ground defense is because Crowder is playing better, our safeties are playing better against the run, and because of Dan Wilkinson. Those factors represent the difference.
Traylor being out a little while isn't going to be a huge deal. It wasn't last year at this time and it won't be this year.
