25. Pittsburgh Steelers (25)PB – 24th, RB – 30th, PEN – 18th


Stud: The best player on this line is Maurkice Pouncey (+5.4), though that speaks volumes about this line and less about him. He does his job, but unlike a lot of linemen in this league he doesn’t pop out on tape as someone who makes a massive difference.


Dud: It’s nice to have a player who can play a number of positions, but the Steelers faithful must be hoping they don’t see an awful lot more of Doug Legursky (-10.5).


Summary: Try as they might, the Steelers can’t field a line that can pass protect and open up lanes. That’s despite a significant recent investment of early-round draft picks. That said, this line was never about 2012, and hopefully a healthy unit next year will justify the hope.
I know some don't like PFF, but they are usually pretty spot on. A lot of the NFL teams use their analytics.

I think they pretty much have it right, this line has some potential in the future, but it was still bad this year due to injuries, etc..
