it is very difficult, extremely difficult, to just make a roster much less hang on. many great qbs, sat, did not play or were traded, before emerging into starters and stars (unitas, farve, moon, theismann etc.). some need to have some patience and let the system work itself out. a 4th rounder is not going to come in and replace a hall guy right away and a team is not going to ditch a hall guy until they just have to. he is in the mix, learning and if the gents give up on him, he might catch on other places.
