In the days following DeSean Jackson’s release by the Eagles, speculation ran rampant as to the reasons why. Everything was to blame from Jackson’s petulant, rambunctious sideline behavior, to his alleged gang ties, to Jackson’s character, to this being Chip Kelly’s fault.

But what a number of sources close to and around the team, including current and former players, as well as additional sources within the Eagles revealed was that Jackson was not very well liked by his teammates, was blatantly insubordinate, with temper tantrums cussing out Kelly several times in front of the team, pushed the NFL rookie coach the way “a child would test boundaries,” and was more concerned with his rap label than he was about winning football games.

Several other sources also suggested that Jeremy Maclin may have had an issue if Jackson returned to the Eagles in 2014. He wasn’t alone, if that’s true.

“The fact is, [Jackson] was a ‘me-guy’ with an attitude problem and [Maclin] is the complete opposite, a team guy, a great character guy you go to war with,” said one source. “Funny how [Jackson] has this anti-bully thing and he thought he could push [Kelly] around; he found out otherwise. His being cut had nothing to do with the gang stuff. The team knew it. Everyone knew he had ‘ties.’ Those were his guys. That’s okay. What put him out was his selfishness. He can try and spin it all he wants how he’s ‘a team player.’ He’s not. I’ll put it this way, when it came out last Friday that [Jackson] was released, more than a few guys were happy it happened. They said ‘good riddance.’ He had no real connection with anyone.

“Yes, you can say he was the type that could catch three TDs in a loss—everyone would be down, but you had the impression he was happy, because he got his. It was all about him. A lot of guys thought that way about him. [Kelly] came in here with a plan to get this thing right, and the one major [obstacle] standing in his way was [Jackson]. If we were going to move forward as a team, he had to go. Think about it—did anyone come right out and back him publicly? Not one.”
