Quarterbacks are more "nurture" than they are "nature."
There are plenty of talented quarterbacks to be had, whether they be second-chance veterans or draftees in any stage of the draft.
The simple fact is that if you have an organization and a team that can support a quarterback, they'll flourish. If you don't, they'll fail.
Take Green Bay, Minnesota, and San Francisco for example.
Green Bay took Jordan Love and developed him with all of the patience in the world. Now they have what most agree looks like a franchise guy. They acquired Malik Willis, a huge bust and a passer who wasn't very good to begin with as a prospect. He's played at his ceiling in spot duty. These guys would have failed elsewhere, and did in Malik's case.
Minnesota is squeezing near MVP play out of retread bust Sam Darnold. This is the first time he's been supported like he's currently being supported, and the obvious talent he's always had is finally coming together with quarterback friendly coaching and a good roster.
San Francisco had JIMMY GAROPPOLO TAKE THEM TO A SUPER BOWL. Is that the type of quarterback you are pining for? No. Geno is 100% superior to Jimmy G in every way except jawline. But success is possible when you've got a team and staff capable of supporting the quarterback! And now they're a juggernaut with Mr. Irrelevant. This isn't luck!
It's not the quarterback, guys. It rarely is. It's coaching, it's development, it's supporting cast, it's environment...
We gotta figure out the system before wasting assets on a quarterback who'll be thrown in a spot to fail. Quarterback will be an easier need to fill after that, and frankly, it won't look like such a need if we fix the system.
