When Mike McCarthy delegated playcall duties to Tom Clements, some believed Aaron Rodgers should just call the plays for the Green Bay Packers.

The thinking went that Rodgers should call his own plays since Peyton Manning appears to.

"Well, Peyton doesn't do that," Rodgers recently told ESPN.com's Rob Demovsky. "Nobody does that."

Rodgers and Manning will call audibles at the line of scrimmage, but they get a play from the sidelines beforehand.

"I think everybody would want a starting point," Rodgers said. "We all have moments where we have (called the plays), whether it's a no-huddle situation or two-minute. Everybody wants a starting point. It's tough to have to call every single play, so it's always nice when you can have a good starting point and you can make a slight adjustment if you have to."

The Minnesota Vikings would like to give Adrian Peterson a more balanced workload this season.

The Vikings are also high on Jerick McKinnon, which could help preserve the legs of Peterson.

Peterson's carries may not decrease as much as his snaps.

“I think it’s more about snaps per game, because that’s what you have to watch in regard to the wear and tear,” Wilson said, via NFL Media. “How he’ll last for the season is the snaps per game, not the carries or attempts per game, because that comes with the territory. He’s going to get his amount of touches that he gets, it’s the other snaps and plays that will determine how successful he is at lasting during the season and being powerful, strong, aggressive and explosive.”

Latavius Murray will enter the 2015 season as the No. 1 running back for the Oakland Raiders.

He "has a chance at a huge year" in new coordinator Bill Musgrave's offense, one team source told ESPN's Adam Caplan, "because he is smart, physically a freak."

Murray came to life down the stretch during his second NFL season, pumping out all but 11 of his 424 yards over the final six games of 2014. His 5.17 yards per carry trailed only four other backs across the entire league.

Walter Thurmond is a veteran nickel corner the Philadelphia Eagles signed as a free agent, who is bidding to become the starter at safety opposite Malcolm Jenkins.

Of Thurmond, Kelly said: "Walt's done a really nice job. He's probably been our most productive guy in the secondary in terms of pass breakups and strips and things like that. He always seems to be around the ball, so he seems like he's fitting in there right now. But again, we still don't have pads on, we're still evaluating guys with helmets and shorts and T-shirts. But he's been very productive so far." 

Marcus Mariota credits playing soccer when he was young for developing his athleticism, fundamentals and intelligence.

"I think soccer is a great fundamental sport -- I think it built a foundation for me as an athlete," Mariota told WGFX-FM in Nashville, via ESPN.com. "Whether that's my footwork now, or relative to just kind of seeing the field and instincts.

"I think soccer is just such a game where you have to understand the complexities and the system of what's going on, and you have to know that before you get the ball. And once you get the ball, you have to react. I think that has helped my growth not only as a football player but as an athlete."
