garret as play caller under wade, had 3 top 10 offenses. one top 2.....the other year top 15 and it was some injuries on the line. so not sure what you refer to for garrett as a play caller.
Callahan never smelled anything close in all his years as a play caller. and the shared responsibilities was idiotic.....and thus Callahan got the boot and if he was so great as many claim, how come he never was even considered for any OC position in the league. he is stuck in Commanders land as OL coach and was passed over by a 32 year old unproven Sean Mcvey……
but somehow, just some how, all these coaches are the awsomest coaches in dallas and get pushed out, yet go other places and just amount to nothing...somehow that's garrett's fault, probably because he sucked out their brains....
Callahan was a crapppy head coach. crapppy OC. got his chance prior to dallas, left dallas and amounted to being only an OL coach, which is what he is good at. nothing wrong with that.
