I doubt any other team would sign Callahan to be their #2, so that leaves two questions:
- Would any team sign him on their 53 man roster as a #3 QB?
- Would any team sign him to their PS?

I think the answer to the first is very few if any.

I think the answer to the second question is, yes, many teams would. Then the Packers have to ask themselves if Callahan would prefer PS on a different team to PS in Green Bay. I don't know the answer to that.

I still think Callahan will make the final 53 due to uncertainty about Hundley.
