Good Lord! I remember him from his last stint here. He was so bad he was released 5 games into the 2011 season, when the offensive line was struggling about as much as they are this year. Unlike wine, I doubt he improves with age!
If it was Breno out there available, yes, get him signed. Not him. The only thing Polumbus ever did above mediocre was block downfield on the Beastquake run.
