Jerry Jones is the real cancer to this organization.
Garrett was the catalyst for propagating that cancer. Garrett was in a position to make positive changes a coach and to put Jerry in his place if needed be - and probably would get away with it.
But no. Garrett was nothing more than a yes man. He knew how to divert blame and throw people under the bus left and right. He was stubborn and never really made any type of adjustments to his gameplan or changed his playbook to accommodate a player's skill or talent. Basically, he was here for the ride. He thrived on the status quo. That's because he doesn't have a clue on how the game works. He is nothing more than a glorified cheerleader masquerading as some kind of "genius" from Princeton. He may not be the "cancer."
Yes that's Jerry. However, he was the catalyst for spreading the cancer throughout the team. This is the results of Garrett letting Jerry do whatever he wanted with the team. He was too chicken to do anything about it. What a coward.
