Too many on here face this question based on emotion and hard headedness, it is a valid question with no way to know the right answer.
Can McCown sustain his solid play? Could we count on him for a season or 2 if a draft pick doesn't work out?
The problem with not signing Cutler is that you are hitched to McCown and a draft pick that hasn't happened. You can't know who will be available to draft when free agency opens. It's very possible all that will be left is the Blaine Gabberts and Christian Ponders. Then you wait a year.
McCown's performance does suggest that what Trestman really needs is a good decision maker, not a flashy arm. That guy might be more like a 2nd or 3rd round pick but would need a year or two. Can McCown hold us over? I have a feeling that if teams start game planning for McCown, get some film on him (recent film) that his success would taper off.
Or does it make more sense to stick with a guy who we know can win games? As stated in the article he was off to his best start early on, would another offseason with Trestman help him buy in even more and drop some of his gunslinger mentality? A lot will say he is what he is and won't change, but Favre was a very different QB late in his career. It stands to reason that Culter could make even fewer bad decisions going forward. It's not like he can't learn.
The draft picks used on a QB would sure be nice to spend on the D. Does it make sense to send away a better than average QB, creating a hole to fill while we have plenty of other holes to fill?
I don't know, no one does. That's why there have been 364 threads on this very topic.
