The one thing I will add , is every qb or offense needs good coaching , playbook, game mgmt, game plans.
Without those being good it is hard to be good, and this is what dallas has lacked since 2007.
Dallas should have beaten the giants in 2007 but they had inferior coaches, wade garrett etc. That cost them a shot at a SB run.
Same thing for 2014,2016,2021,2022.
Coaches make a difference, and jerry wont hire a good HC , tries to create a OC in kellen, tried to create a HC with garrett, and he
hires Mike, cause he heard bells, and he says he wants mike here a long time lol.
I dont think mike is a good HC, he is avg, typical nfl HC. Him getting cowboys to a SB is unlikely, and winning one is even more unlikely.
I read here all the time how many weapons does dak need? lol, but how many does Mike need??
It all starts and ends with coaching, not the QB.
And I am not a fan of dak, but no qb can be good consistently, or in big games, with bad coaches.
