Jonathan Martin prefers to play LT and was considered to improve when playing there last year.
Richie Incognito prefers to play RG.
Eric Winston in Houston was considered one of the best Zone Blocking RT in NFL just season before last and is reportedly willing to sign a 1 year contract for $4m and has no real injury concerns.
Jonathan Cooper is considered to be one of the most athletic LG to have entered NFL draft for years and is ideal for ZBS.
I would prefer this over any trade for Brandon Albert, who is looking for a massive contract and has lingering injury concerns.
I would be happy going into 2013, with a line consisting of MARTIN-COOPER-POUNCEY-INCOGNITO-WINSTON
