I'd put Callahan out there just to find out if either one of them is worth keeping around next year or if I need to start the entire backup process over again. You really have no idea what someone is made of until you put them in a game situation. Callahan has been in the system long enough that you should be able to run a decent sized chunk of the offense and he actually didn't look too bad in some exhibition games.

This is a far-fetched example, but nobody ever though Brady was going to amount to anything except a 6th Rd. potentially competent backup until Bledsoe got hurt and he had an opportunity to show what he was capable of doing in a game. If Callahan bombs BFD. He wouldn't be the first or last brutally terrible backup or even starter we've had in GB. I just haven't seen anything out of Hundley that would make me want to invest much more time into him and it's not like we're going anywhere this year anyways.
