Obviously, a player lost for the year is never good news. Considering it is a member of the much maligned offensive line doesn't help either.
However, I don't see how this o-line (by Pittsburgh standards) could get any worse.
Silver Lining: Marcus Gilbert is a very capable 2nd round draft pick, add that to the fact that he's young and was teammates with Pouncey at Florida. That youth and, most importantly, chemistry of those two might be a boost.
I'm all for any opportunity for us to get younger and gel better as a team.
