Archer asked whether we should bring in Todd Brandstater to challenge McGee. I wonder why we need a 3rd QB at all. When we are trading off between the possibility of needing a 2nd kicker, an extra D-Lineman, a Fullback, 4th TE, 6th WR, or an extra O-Lineman, Linebacker or DB. Any of these players could help the team more than McGee.
1. McGee isn't worth a roster spot
McGee is not going to be the next Favre/Romo/What have you. There is no buzz about how great he looks. If he were special, somebody would be saying something about it by now.
2. We don't have the staff to develop young QB's
I remember when we drafted McGee, people pointed to Green Bay's example of drafting young QB's every year, developing them, and trading them for higher picks. The problem is we don't have a David Lee or an Andy Reid to develop young QB's. Wade Wilson coached the worst QB tandem in the league in Chicago and has never brought a young QB along. There is no reason to believe he can turn McGee into anything.
3. If (God Forbid!) Romo and Kitna go down, McGee would still probably not play. We would go out and get the best veteran QB on the street.
Again, I see no reason to keep McGee (or anybody else) around as a 3rd QB.
