I have been watching NFLN's Top Ten LBs and Top Ten defenses this weekend. There seems to be a common theme among the two. Teams that have great coverage LBs seem to have great defenses.

Granted there are other factors that go into making a great defense. I also concede that you can't just throw three coverage LBs back there and win a Super Bowl. But I wonder if fan and media nations love for the Dick Butkus style of play has contributed to the common thought that great (non-pass rushing) LBs don't impact success as much as other positions.

I take a look at the best defenses, both of all-time and recent history, and they all seem to have a guy or two that can take away 1/4 of the underneath zones while not being a negative against the run.

Am I using bad logic here? Or will Aaron Curry (if he is as good as we hope/think) make the rest of our pass defense look significantly better?
