The Pittsburgh defense, which got off to a bit of a slow start this year, is now playing its best football and still hasn't even played a fully healthy game since midseason.
If LaMarr Woodley can be healthy, watch out. The Steelers are playing the best defense of anyone right now.
If there is one thing that comforts me as the Steelers head to Denver next weekend, it is that Tim Tebow will be playing his questionable brand of quarterback against the best defense in the NFL. That's not a good recipe for a guy whose best games include 1930s-style passing numbers.
Jason Worilds has emerged as an energetic pass rusher who will likely receive time in the playoffs even if Woodley is back for the majority of each game. He's too fast and too good to leave on the bench and seems to be a good option for third-down pressures, where the team is still working to improve (and where they were excellent on Sunday).
The pass rush has been better and better in recent weeks, something that was missing early on. The turnovers are coming now, too, as the secondary starts to benefit by creating mistakes as quarterbacks run away from the linebackers.
The Steelers defense will have to be good against some of the better offenses in football, which await them if they make a deep run. Right now, they look like a Super Bowl unit.
