Not saying he's the best all-time, because I never saw some of the older great ones play (e.g. Jim McMahon), but I think he's the best in the last 25 years.
Yeah, there were some guys who put up huge numbers (Cam Cooper, Riley Nelson, etc.) but from a "total package" standard, I think Dart is the clear leader.
Big arm.
Football intelligence.
Big frame, strong body.
Good height.
Pocket presence.
Accuracy.
Running threat.
If there's any shot at landing a kid like that, you do everything to get him. It would be tough to unseat Jaren because of Jaren's experience in the system, but from a physical standpoint, he's already on par, IMO. He'd have a great shot at starting in 2023.
