Just because he won't be the 10 year franchise guy, doesn't mean you can't get 5 solid years out of him.
At this point you're gonna either have to hope an Aaron Rodgers type falls to you in the first, you groom a second/third round guy, or you pick up a free agent. The franchise guys are all gonna go top 10, and maybe top 5. Do we really want the Bills to be drafting there? And just because people here would give up an entire draft for a player, I'll pretty much guarantee the Bills won't.
So again, at this point you're gonna have to give the reigns to Fitz for probably at least the next 3 seasons and maybe 4 in order to draft and develop the next QB. Because at this point, if the QB they pick up is in the draft, he'll need a couple of years to learn. Fitz may not be great, but he's gonna be better than most any rookie they could pick up for the first season, Luck included.
The last thing we want to do is draft another 1st round QB, and then put him in primetime too quickly. Look how well that worked out for us last time.
Unless Levi Brown miraculously develops into a stud.
