None of that will or should happen breh
Garrett has had tons of chances to make it work and tons of talent. This time all he had to do was have a gameplan to feed his RB and don't give ARod all day. That's it. This time Jerry made it simple for him and he still fukked it off.
From this point forward all GB has to do is make the Cowboys offense work and only give up field goals.
I wouldn't know who he'd hire (Maybe Kyle Shanahan) but Garrett ain't the person who's getting them to the next step.
