Fox: Both Tebow and Quinn can and will be No. 2 QB - BroncoTalk:
'via Blog this'
John Fox has announced that he doesn't have to and won't name a number 2 quarterback.
This is because of the new rules for dressing 46 active players, instead of 45 active and one emergency third-string backup quarterback, Fox says, "It's a competitive disadvantage" to announce a backup quarterback. The rule changes help Tim Tebow who will possibly be used in short-yardage plays, in the red zone, or as a decoy on the field periodically this season. Brady Quinn will be the 'functional' backup number two guy.
