Pro Football Focus grades out linebackers in run defense, and Green Bay Packers LB Desmond Bishop grades out as the best by tackles. Then they change the measurement by looking at Run Stop Percentage instead of tackles, and it turns out he's only one of the best. But there are some other factors that make this analysis complicated.
What isn't complicated is that there's no mention of A.J. Hawk. That's no surprise since he wasn't very good last year. I'd be stunned if the Packers replaced him next season, but he won't last much longer if he doesn't turn it around in 2012.
Back to Desmond Bishop. While he rarely came off the field, except for a couple games when he was hurt, he had the fewest run snaps of nearly every linebacker mentioned by Pro Football Focus. Teams didn't run the ball a lot against the Packers, so Bishop doesn't have as many stops. He wasn't often (maybe never) in a situation where his opponent was obviously trying to run out the clock last season.
Also, Bishop was asked to play run defense on a team that played in the nickel on about 75% of their snaps. Many times, there wasn't a defensive lineman in front of him to occupy the offensive linemen, and he certainly had to fight through many blocks to make plays.
He's a good inside linebacker and nothing here that really changes my thoughts on him. He grades out well statistically, even with a couple of factors working against him in their defensive scheme.
