Anthony Spencer is a complete 3-4 outside linebacker who drops in coverage more than his counterpart Demarcus Ware due to playing on the strongside.
Spencer still has occasional snafus in the running game, but it is a strength and he will only get better at it with experience.
He's the best outside 'backer in coverage on the team.
And while sacks have proved elusive this season, he is getting regular pressures and hits on the quarterback.
I wish nfl.com would track "pressures" to make it easier to keep track of, the teams do it and it's a very important stat.
I'm not concerned about Spencer, the sacks will come and he will continue to improve.
At the same time, I'm very disappointed in Wade Phillips not having a rotation going by now. Victor Butler deserves more snaps and even Demarcus Ware should get some plays off every week on defense.
Alternating defenders, whether it's a three man or four man group, will make the entire unit better in the long term.
It's a mistake to just think about the week at hand, you have to also consider what will help you down the road.
