I believe there’s been an understanding for awhile that if Garrett wanted the Giants gig, and it was available, he would get it.
I believe that’s why he was the one who didn’t want the extension with the Cowboys.
If the Cowboys had a good season, and Jerry wanted him back, he could have told him, “Ok, I’ll coach for you, but I want to pick my assistants and have total control over player personnel.”
As it turns, out, now parting is the best for both parties, because Jason will end up in a much better situation in New York.
That’s just my conjecture, I could be wrong.
Not sure Jerry will let him go too soon. His contract ends Jan 14 and Giants are in the NFC East too.
