How Good Is The Steelers Offensive Line This Season?

I've read from various sources that the weak link on the Pittsburgh Steelers this season is their offensive line. It's easy to see why when you look at their roster. Their starting left tackle is Jonathan Scott, who's been cast off by different two teams (Bills and Lions) in his five year career. Their starting right tackle is Flozell Adams, who did not appear to receive an offer from any team other than the Steelers after the Cowboys released him. They've been forced to start them because Max Starks suffered a season ending neck injury, and Willie Colon tore his achilles.

Football Outsiders has the Steelers offensive line ranked No. 19 overall on run blocking and No. 29 in pass protection. Their struggles are a good reason why RB Rashard Mendenhall was only ranked No. 22 overall. And they got more bad news this week as they'll probably be without their injured rookie C Maurkice Pouncey. 

However, Ben Muth praised their performance in the AFC Championship game. I'm not a fan of the Jets defensive line, and I chalked the offensive line's performance up to a weak game from them. But Muth saw Scott and Adams doing a much better job at run blocking than he'd seen from them all season, and they deserve a lot of the credit for Mendenhall's big game.

What do you think of the Steelers offensive line? Do you think they'll have a much harder time against DE Cullen Jenkins and NT B.J. Raji?
