Keisel missed about 2 games but is practicing and will play at his usual defensive end spot on Sunday when the Steelers host the Titans.
He was there in the week 1 blowout to the Ravens, but he was there for the week 2 win vs Seattle. It's hard to hold that first game against any of them single handedly. The entire team played like crap but clearly Brett's presence has been missed. If you remember, Lynch did next to nothing and the Steelers were able to shut down Seattle. Now obviously Keisel wasn't the only reason they won that game. However, without him being in the lineup the last weeks it has been noticeable.
Getting the bearded beast back is only going to help this team if you think about it. He's an underrated lineman who is tough enough to hold his own against the lineman to stop the run but also can get some good pressure in the pass rush. Ziggy Hood has been somewhat unimpressive in relief of Keisel. Besides, Brett is the youngest of the starting 3 and the only likely one to still be around in 2012. At that point he'll be the elder statesman of the starters.
