OL: Besides the obvious, which young guard is going to emerge?

The mystery of Big Foot continues. The Bengals won't be able to get a foothold on right tackle Andre Smith's second straight offseason surgery until the lockout ends and, as head coach Marvin Lewis has said, they need better play at that position. The other mystery is Anthony Collins unable to get into the lineup with Smith shelved. In the nine games Collins has started the past two years, the Bengals have rushed for an average of 110 yards and are 7-2.

Until Smith's foot gets figured out, the big question is how hard do 2010 fifth-rounder Otis Hudson and 2011 fourth-rounder Clint Boling push incumbent left guard Nate Livings? Or does Livings get more consistent in his play? The Bengals are going to want to work on Boling's technique, but they like his brains and versatility. Still, the last rookie lineman to start Opening Day for the Bengals was second-rounder Eric Steinbach at left guard in 2003.

Now the thing that gets me is the fact that when Collins is starting, the Bengals are 7-2 and average 110 yards rushing.  I really wish it would show the stats when Roland was in, but im guessing its a lot worse.  I would also put Reggie Stephens into the starting mix at either center or even gaurd.  Livings cant start, Boling or Hudson have to be better than him, they atleast cant be worse.  Stephans looked great at center when he played, and the I think Cooks way to overated, so I would like to give him a fair shot at center.  If the Bengals start Collins, or Smith is in shape and good, and any of the 3 young guys can be a good starter, the line has a chance.  That all being said, we are probably looking at a Whit, LIvings, Cook, Bobbie, Roland starting oline, because for some reason thats what Marvin likes.
