The belief that the Eagles are operating their multi-billionaire dollar organization purely with the goal of fostering a personal vendetta towards Chip Kelly is approaching 9/11 Truther levels of delusional.
Sports teams are toys for rich people.
Probably the best toy a person could buy for him or herself.
I could easily see an owner trying to get back at Chip if it made them happy. I mean Jerry Jones fired the head coach of the possibly the greatest football team of all time because he thought the coach was getting too much credit. Al Davis had a bat phone to call down plays during a game.
I don't now if it is true that the Eagles are just trying to erase all memory of Kelly irregardless of whether or not it made sense, but it would not be out of the ordinary for the NFL or sports teams owners in general.
Just think of the crazy shit you would do if you were a bored billionaire with your own football team.
