TLEH
Pronounced T-Lay
With a quarterback who can make plays with his legs, it basically wipes 75% of all QB's who played far enough back to be able to view their career arc. Randall Cunningham fits your request and really that's about the only style of QB that is a valid comparison. Jake Plummer also evolved once he went to Denver. Drew Bledsoe? Not even near the same type of QB, so asking if he can become a statue who only relies on hitting route trees and not running at all is an entirely different style that no one would want from Fields anyway. Numbers won't show it, but Vick evolved into a more traditional QB when he was no longer the fastest guy on the field and defenses evolved to cover such a wildly different type of QB.
Point is, you're asking for historical data to compare what was expected of traditional pocket passers (high completion percent) and applying it to someone who in the best case you wouldn't want to be a pocket passer anyway as it would devalue what he offers. He can win a game going 10-25 if he also has a lot of quality rushing attempts and is gashing defenses with a few runs to keep the defense honest. He's never going to be 27-32 350, 3 TD's, 1 INT.
I'm not asking for a stylistic comparison. I'm asking for any comparison.

Not like it takes some athletic freak to play the position. I think Jalen Hurts is a good comparison when it comes to Fields and what he could be on a great team.. But the Bears aren't the Eagles. I'd rather be a team like the Chiefs or Patriots are/were and get elite QB play and use that to overcome your deficiencies, rather than have an amazing team and hope your QB is good enough. A lot harder to do.
