By the way, Brad Allen did NOT meet with the Lions coaches before the Dallas game, which might be the real reason he is out for the playoffs.
Where was he, on Jerry's hooker bus?
I would not list 3 active QB. You are going to want to rest some more important players to take up a space on the roster for a last game
Make Hendon your backup for Week 18 so he gets some jitters out now (although the way they talk this dude is cool as the come), Make Teddy your playoff backup.
The NFL has rules for the third quarter. They can only enter the game because of injuries.
I think that's only if you have two quarterbacks on the ACTIVE roster for the game (if you list the 3rd QB as the Emergency QB). If you list three active QBs you can use them how you want.
