Fox said Manning is a player who "raises all boats," with his work ethic and determination rubbing off on teammates on both sides of the ball. He said he saw that play out even in the offseason.
"Part of learning a profession, or getting better, or mastering, or improving in a profession, is watching guys who have done it very well or done it great," Fox said.
Running back Lance Ball said offensive players are driven to please Manning.
"He's a player/coach, so he wants things precise, he wants you to be at a certain point at a certain time, just know your stuff and just work hard," Ball said. "Guys put a little pep in their step. They want to make sure they're on point and right, and pleasing the coaches and also Peyton."
Cornerback Tracy Porter, who played the last four seasons with Drew Brees in New Orleans, said Manning makes Denver's defense better, too: "Because facing him forces you to really practice and lock in and watch film and be on top of your technique," Porter said. "Because you don't want to go out to practice and have these guys seeing you out of position. Because they see things before it happens, those Hall of Fame quarterbacks. And you don't want to get the ball thrown at you that often in practice."
Manning hasn't played in a game since the Colts' wild-card loss to the New York Jets following the 2010 season.
"I have missed it, and I've never taken it for granted to be out there playing," Manning said. "... I've always felt very fortunate to be playing in a game for a living."
Notes: WR Brandon Stokley (flu) was the only absence from practice. DT Justin Bannan (calf) and rookie DE Jamie Blatnick (ankle) were limited. ... Rookie WR Eric Page, who had a chance of making the team as a returner, was released after blowing out a knee last week.
