First I gotta say I'm not a fan of Pees mostly because every year we've seen this team lose games by blowing 4th quarter leads.
The defense did improve a lot statistically this season, and I was happy to see more turnovers as well, but a Top 10 defense should be able to make some of those critical game winning stops.
Pass rush wise, we just need guys that occasionally beat their man one-on-one, its good to see different blitzes but ultimately guys have to win some battles in the trenches. Early in the season Jernigan was killing it, getting QB hits, pressures and sacks and didn't see as much from him down the stretch as far as impact plays. Suggs was playing with one arm all year and still was the most effective pass rusher, still getting double teams ( which only strengthens the argument that the other guys opposite of him need to win their battle occasionally. )
Dumervil obviously was never himself this season with the injury and explosiveness.
Judon- shows potential, but he wasn't played enough early on during the season.
Z.Smith - I don't know if he lacks the power to beat blocks or if it's all poor technique but he seemed to regress.
It still irritates me that McClellan got so much PT defensively and Correa a 2nd round pick barely saw the field. If McClellan was an edge setting like JJ or Upshaw I could understand.
