Nice work on the graph so thanks for that.
Looking at it it appears that in my estimation to be considered a “franchise” QB the second year wins benchmark looks like 10 wins.
The only anomaly appears to be Dalton but he also had one of the highest win marks year one indicating a strong Bengals team regardless.
Newton is the other exception to the rule if you consider him a franchise guy as he didn’t meet the ten win benchmark year two. Personally I don’t as he is pretty terrible at throwing the ball and more running QB than throwing one.
Ten wins by Allen this year will be huge and hopefully cement himself as a franchise QB.
