Yeah, we've all heard all of this for quite some time. I'm not sure anyone tried to dispute that some (maybe most) of the Eagles didn't like Chip for one reason or another. As I said, let's give it some time and let all of the reactions come out to see what's actually true and what isn't. Also, again, many players just back their teammates regardless of what they say because that's what teammates do. It seemed pretty clear that Chip had worn out his welcome in Philly. Most of that animosity was caused by the moves he made as GM. Even if they bring up things like tough practices, etc...it really started getting louder after certain players were traded/released.
Everyone loved him after the first season when they went 10-6 and made the playoffs. I remember reading one article in particular before his 2nd season where players praised Chip for how he went about things...one of the loudest was....yep, Shady McCoy. McCoy had two unbelievable seasons with Chip running the offense he played in...then he got butt hurt that he was traded and decided to call Chip a racist (which was fucking laughable, at best) and act as if Chip was this demon of a coach or something. That's clearly just someone who's frustrated/hurt/upset who was just venting and making stuff up, and Shady still holds the grudge over the trade and has chosen to act like a petulant child anytime the subject is brought up, refused to take his calls, refused to shake his hand...basically Shady is an adolescent who couldn't get over the fact he was traded.
None of this has anything to do with whether or not Chip can coach in the NFL, which is what nbafan also said, and what he got some push back about. I'd imagine you can go into most NFL locker rooms and find players on every team that don't like the coach...that's just how it goes. Harbaugh wasn't liked by a lot of his players, especially towards the end of his tenure. That has nothing to do with whether or not Harbaugh can coach in the NFL, which he clearly can do.
There are other articles out there painting Chip in a worse light than this one too. Many of the comments in this article, from the players, say that they didn't really have an issue with Chip. Again, I'm not disputing that many players probably didn't like Chip Kelly, but I'm not sure this article really does a good job at all of showing that. Most of the comments were from the owner Lurie....and he's a major part of the problem himself. Chip was held accountable for his decisions...as a GM, not as a coach.
