As a rookie, Perkins was transitioning from being a 3-point DE to a 2-point LB. He's had a great mentor in Judon. However, the injury during camp last season clearly curtailed him. I know a lot of people wrote him off, but this is only his 3rd year. This is the year he needs to start getting reps and making waves. Doing that now, is a good thing.
Being able to roll out Judon, Uche, Perkins and Jennings with White and Wise for Jumbo/inside DTs should really keep them fresh. Seeing Perkins get "2 sacks" today is nice, but it will be better if he does it in Pads.
