It’s not that Jerry likes Garrett. It’s that he LOVES Garrett like a son. He has said as much many times. He’s known Jason since he was a kid. Garretts dad even worked for Jerry, as a scout, at one time.
I’ll give this to Jerry. Loyalty, Family, and relationships mean ALOT to him. If you’re a player that is in the family, he’ll always treat you like you’re part of it. While part of the problem is Jerry wanting to prove himself the greatest GM/Owner in the world, the other part is that he really is too loyal to his inner circle of people.
