Chip Kelly admitted most of the Philadelphia Eagles' moves this offseason were about changing the team's salary structure and not the culture.

“Almost all the maneuvers we made with people going out were because of contracts,” Kelly said, via CSNPhilly.com. “People making too much money in our opinion of what the evaluation for what the pay for play is. Every guy we released, we offered in a trade to everybody in the league, and no one took the trade. Why? Because the contract is too high. [They] all sign somewhere else after they get released for less money than they were getting paid because you’re not going to trade for that.”

DeSean Jackson and Evan Mathis were productive players for the Eagles but were overpaid, which is why Jackson took less money with Washington and Mathis remains unsigned.

“They had one common denominator — they were all very expensive,” Kelly said. “I think that’s just the nature of contracts in this league. A lot of them are back-end loaded. Then decisions have to be made. So guys are making $10, $11 million a year, you have to make a decision on them.”

ESPN has made some changes to their formula for total QBR, which has become a widely used metric to evaluate quarterbacks.

How interception returns, pressure and credit for yards after the catch are factored were changed.

Russell Wilson's QBR increased by 8.2 points, moving him from 12th to eighth in the rankings. Wilson was one of the top players in the NFL when under pressure.

Aaron Rodgers' QBR decreased by 5.2 points, but he remained ranked second. Rodgers' QBR decreased due to how the new formula handles yards after the catch.

Geep Chryst does not believe Colin Kaepernick regressed during the 2014 season.

In what became the final season of Jim Harbaugh's tenure as head coach, Kaepernick had a career high in passing yards and his completion percentage improved but he threw more interceptions, fewer touchdowns and also took 13 more sacks.

"Last year, you're playing with some different sets of challenges," Chryst said, via the San Jose Mercury News. "There was more change within the offensive line than he had experienced the last couple of years. How does that affect your production as a quarterback? You're behind more often in games. How does that affect your production as a quarterback? I cite the fact that we had six touchdowns nullified by penalty. You plug that back into his formula, he really wasn't ... he didn't regress off his line as much as perceived."

Adrian Peterson wants to rush for 2,500 yards this season and Mike Zimmer has said he'll get enough carries to make that possible.

"As much as he can take, and as much as he can handle in all the things that we're doing," Zimmer said, via USA Today's Tom Pelissero. "Obviously, we're going to have to spell him at times like you do a lot of guys. But we get down on the goal line, and we're probably not pulling him out, you know? He's our best player, and we're going to continue to use him."

The Vikings will pay Peterson $26 million over the next two seasons.

Peterson missed 15 games last season due to his child abuse situation.

Kurt Warner has been working with Colin Kaepernick this offseason and he believes the San Francisco 49ers would be best served by not using him on designed runs.

Warner said Kaepernick should only run when there's not a pass option from the pocket.

Kaepernick averaged 39.9 yards per game last season on 6.5 attempts, up from 32.8 and 5.8 in 2013. During the 49ers' two playoff runs with Kaepernick, he averaged 88.0 and 81.0 yards per game rushing respectively in 2012 and 2013.

J.J. Watt has the top spot in the NFL Network's list of Top 100 Players of 2015.

Watt finished ahead of Aaron Rodgers and became the first defensive player to claim the top slot since the series began in 2011.

Tom Brady, DeMarco Murray and Peyton Manning rounded out the top-5.

The Top 100 voting was done exclusively by NFL players.

Richard Sherman is ahead of Darrelle Revis on the NFL's Top 100.

Sherman fell four spots to No. 11 in the 2015 edition, ahead of fellow cornerbacks Revis (No. 17) and Patrick Peterson (No. 19).

Revis made the leap from No. 37 last year and 67 in 2013 after finally recovering from a torn ACL.
