PHILADELPHIA (CBS) — Howie Roseman and Chip Kelly couldn’t make it work.

Roseman was forced to give personnel reigns to Kelly after the former Oregon head coach went 20-12 in his first two years with the Philadelphia Eagles. But after a slew of controversial moves, many of which did not pay off, Roseman is back in charge and Kelly is, well, in San Francisco.

Roseman, on Tuesday’s Colin Cowherd FOX Sports radio show The Herd, admitted that he deserves some blame in the power conflict between him and Kelly.

“I look back and there are certainly things that I could have done a better job with, there’s no question about that,” Roseman told Cowherd. “I was with someone for a long time in Andy Reid. Professional and personally, couldn’t been closer and maybe then you take for granted sometimes relationships and how — like with your wife and hopefully she’s not listening right now — you gotta work on them. I learned a lot from it and I learned a lot from Chip, no question about it. Our organization is better because of some of the things he brought here.”

Last season, with “Chip’s players” the Eagles finished 7-9 and Kelly was fired before the team’s final game of the season. Roseman took the year to learn and grow, which he says, has made him better personally and professionally.

“I had a great opportunity over the last year — which I certainly didn’t feel like at the time that I was going through it — to take a step back and really kind of analyze where I was and then as a whole meeting with a bunch of leaders of teams in different sports,” Roseman said. “Major League Baseball, the NBA, NHL, former GM’s of the National Football League, and EPL leaders as well. And I’m so much better personally and professionally than I was the last time I had this opportunity. So, maybe it was preparing me for this, but I feel great about it. We’ll see on the outcomes, but I know the process is right.”

Last week, Roseman completed a tactical offseason in which the Eagles moved up from pick No. 13, to No. 8, finally to No. 2 in order to select 6’5″, 240-pound quarterback Carson Wentz from North Dakota. Kelly and the 49ers selected Oregon defensive end DeForest Buckner with the seventh overall selection in the first-round.
