I think he makes the roster at this point, but ultimately I don't think he should.
I might be tempting fate, or Karma, whatever, but I don't think the backup quarterback will play a large role in 2014, and I sure as hell hope it doesn't.
I'd rather see another player get the roster spot to develop.
Mallet has no trade value as I see it and unless things go horribly wrong will provide little benefit to the team in 2014 and certainly 0 benefit in 2015 and beyond.
BB does not believe in tanking a season for draft position and neither do I, but BB will be more cautious than I would.
He makes the roster, but he hopefully shouldn't ever be needed.
