Here's how quickly and thoroughly Chip Kelly alienated himself in Philly

Everyone knows the Chip Kelly experiment was a failure in Philadelphia.

But now we are getting firsthand testimony about just how disastrous it was.

A former member of the Eagles' front office shared some dirt with NJ.com, claiming Kelly overruled and alienated the scouting department soon after his arrival. The 2014 draft was a particular source of frustration:

The Eagles surprisingly drafted defensive end Marcus Smith with the 26th overall pick in 2014, prompting this reaction from the source of the NJ.com feature: "Personally, I had Smith with a third-round grade. That was one of the shockers of the first round -- that he went as high as he did."

And things continued to go downhill for Kelly in terms of his roster decisions and relationship with those within the organization --€“ not to mention the team's failure to return to the postseason after winning the NFC East in 2013.

Kelly, of course, was fired before the final game of the 2015 regular season that saw the Eagles finish at 7-9. He is the new head coach of the San Francisco 49ers, with whom his say in personnel decisions likely will carry far less weight.
