How Much turnover/devolopment Needed for new Coaching Schemes?

242 (2023) 182 (2022) 146 (2021) He’s not a mobile QB.
Dak has more than half of Carr career yards in 3 yrs. Amd twice as much yards then derek carr career total. Dak is a pass first qb but he does have the ability to run. Derek carr has almost 0 mobility. Doesn't run and can't run is 2 different things

And I never said rushing I said mobile like ability to move the pocket escape defenders in backfield etc.
