RT- There are two choices here, Tony Pashos and Brandon Keith. Keith is younger but had an overall negative rating. The caveat is that is that most of the negative came from his first two games starting and he stabilized to neutral for the rest of the season. Pashos grades out quite positively (+4.4, +9.7 pass pro) with 12 games at RT. He's 32, which isn't young, but still not ancient. He also didn't grade out as a great run blocker... but seriously beggars can't be choosers.
OT Chris Williams is a possible option. He has been rumored to be on the trading block if he loses his starting job with the Bears. Fairly young guy who hasnt really worked out to be what they hoped but has experience at RT and LT.
Could be an option
... good posts!
... if we upgrade RT even to slightly below average we can still make some noise this year ...
