True. It doesn't mean anything to me. I should have clarified it that way, because it clearly means something to you. Which is fine.
For every example you provide, I can counter it with examples using the same players. For example. Kurt Warner had a 2-8 record his first year with the Cardinals, and Josh McCown had a 3-3 record. Who was the better elevator? He was 1-4 as a starter the next year and Matt Freaking Leinart was 4-7. Year after that he was 5-6 and Leinart was 3-2. As far as winning percentages go, both are better than Warner at elevating players. Right? Besides that, why would Warner wait 3 years to elevate everyone? That seems kind of odd. Why not do it right away?
And the worst offensive line in SB history? Hardly. They were ranked 9th in pass protection. They just couldn't run block very well. And if you tell me that Warner did that, then why didn't he do it the other years? When he left, they simply had no one even remotely close to being a backup as their starters. Anderson, Skelton, Hall, Kolb, Lindley, Hoyer? lol. Same with the Colts. You're probably better than Curtis Painter. Where are any of these guys now?
But let's use your argument again. If the Rams are trotting out a beat up Bulger, a washed up Boller, and a never was in Keith Null, and that team won exactly one game, then Bradford coming in and winning 7 (I don't subscribe to QB wins, btw), clearly makes him an elevator of men, yeah? That's what you're telling me, anyway. And what a magnificent supporting cast HE had at the time too, huh? So, if you claim elevation is a "thing", then Bradford has it. I claim it's not a thing, but it's instead a team sport with varying degrees of talent at 22 different positions, and the production of the QB can be directly proportional to the support he has at the time + a myriad of other factors. That's not to say all QBs are created equal. Merely that good ones need help too. Elite ones can get by with less. crappy ones are always going to be crappy.
