What's old (back up) is new (back up) again

Guess who's just been re-signed to be a #3 QB? Craig Nall. Remember him? He was drafted by the Packers in 2002 and spent four seasons with the team before leaving to try to get a starting -- or at least better back up gig -- with Buffalo in 2006. He was released by the Bills earlier this season and spent about a month with Houston before being cut last month. Apparently, the injury to Brett in the game against Dallas made the Pack want to gain a bit of depth at QB going into the last 4 games of the season and the playoffs. Obviously, Nall would be a good fit, knowing the team as he does, although he departed just as Mike McCarthy was coming on board. So, like Brett and Aaron Rodgers, he will have to get up to speed on new terminology. To make room for Nall, the Packers once again cut safety Marviel Underwood, who was signed the week before the Dallas game to provide depth in the defensive backfield which had been hit with injuries.
