The passer rating Jackson put up in 2019 is better than any of Steve Young's complete seasons. It is also substantially better than the best seasons of any of the guys you list except for Wilson. (And, it's better than Wilson's best, too, but only a notch better).
If you want to find an antecedent for Jackson, you have to start by finding someone who's capable of putting up one of the best passing seasons in NFL history. (#8 all time in passer rating). Young, Daunte Culpepper, and Wilson are the only three on the list of 110+ QB rating seasons (n=17, min 400 attempts) who've had a rushing season over 500 yards. If you drop it to 105 QB rating (n=33) you add Cunningham's 1998 (a season when he rushed for 132 yards). Drop it down to 100 (n=72) and you add Donovan McNabb, Deshaun Watson, and Steve McNair.
So, start with the list of:
- Young
- Wilson
- McNabb
- McNair
- Culpepper
- Cunningham
Speculate where Jackson will end up on that list as a passer. And add in the fact that he's is a better runner than all of them, by a lot.
