BOCA RATON, Fla. -- We now have Chip Kelly's version of why things didn't work out with the Eagles.

Speaking for the first time with the Philadelphia media since being fired prior to Week 17 of last season and hired by the San Francisco 49ers, Kelly made it clear that he knows he was fired because he didn't win enough games.

"I was surprised," Kelly said. "We had spent the whole day game planning and at practice. Not something we saw coming."

He also made it clear, however, that he wasn't happy with the front office structure of the organization.

Without mentioning him by name, Kelly said he wasn't happy with the way the front office was being run with Howie Roseman involved, and his concern grew once Tom Gamble was fired last offseason.

"I didn't like the direction it was heading," Kelly said. "I didn't think we were on the same page."

Kelly said he expressed his concern to owner Jeffrey Lurie last offseason, who then decided to give the head coach full control of the personnel department.

"We met after the season and discussed what was going on. It ultimately was his decision," Kelly said. "But I didn't ask for anything...I would have been content to just go hire a general manager."

Once Kelly was given control by Lurie, Roseman was moved to the other side of the building and no longer was involved in evaluating talent.

Roseman, however, remained in control of the team's cap, and was responsible for writing the contracts handed out to players.

"I have never negotiated a contract in my life," Kelly said. "I had nothing to do with any contract."

During this past season, Kelly said he hardly communicated with Roseman.

When asked if the person in charge of personnel should be in communication with the person controlling the cap, Kelly agreed.

"Yeah, you would think," Kelly said. "(But) it wasn't set up that way."

With Kelly running the personnel department, however, the team went 7-9 last season and missed the playoffs. His decisions to being in Sam Bradford, Byron Maxwell and DeMarco Murray all backfired, three big decisions that made many question if he was capable of running a personnel department.

Now with the 49ers, Kelly raved about how the front office works in San Francisco, and made it clear that he trusts the talent evaluations of general manager Trent Baalke and Gamble, who is also now in San Francisco after being fired by the Eagles.

"Whenever you are working with anybody, (trust) is a huge component in terms of how things work on a daily basis," Kelly said of Baalke. "He has a proven track record. It isn't trust without evidence. There is a ton of evidence of him being able to put together a really good football team."

Kelly was fired by the team Dec. 29, 2015, just one week before the end of the 2016 season. He finished his time with the Eagles with 26 wins in three seasons, including one division title.

The team has since hired Doug Pederson to replace Kelly, and Roseman is back in control of the personnel department.
