Let's just assume for the sake of argument that BB decides against signing a veteran to be the back-up, and pencils in Matt Cassell as the back-up. Who wins the battle for 3rd stringer? I don't have NFL network and wasn't able to see Mortensen play. Bramlet is a rookie, and I didn't see any Wyoming Cowboy games last year. Perhaps BB is trying to get some developmental youth at the QB position as a whole.
