Peyton Manning begins working on Denver Broncos' new offense

ENGLEWOOD, Colo. (AP) Keep the ice packs in the cooler. Hold off on that rocking chair.

Declaring he feels good both physically and mentally, Peyton Manning made it clear Tuesday that he doesn't view the 2015 season as his farewell tour.

''I wouldn't call it that. That's not how I see it,'' the 39-year-old quarterback said in his first public comments of his offseason.

He stressed that he views such chatter as neither offensive nor motivating as he prepares for his 18th NFL season.

Manning spent several weeks mulling his future after Denver's playoff dud, a 24-13 loss at home to his old team, the Indianapolis Colts. After deciding to put off retirement, he accepted the first pay cut of his career, giving the cash-crunched Broncos $4 million to address their roster needs.

Manning declined to discuss those matters Tuesday, saying he was focused on learning the new offense under a new coaching staff. He also demurred when asked about the challenges or nuances of running the new hybrid offense.

Coach Gary Kubiak and his quarterback began meshing their philosophies in earnest during their first minicamp workout together. The highlight: Manning practicing roll-outs that were reminiscent of his father Archie's playing days.

''I like to think I'm pretty versatile, believe it or not,'' the notoriously slow-footed Manning said with a chuckle. ''I feel like I can execute whatever plays the coach calls.''

Kubiak said that while the mashup offense is a work in progress, ''today we had no problem as far as functioning and operating. For us as coaches, there were two systems going on out there today. I think the players can handle it. It's not a problem.''

Four days after general manager John Elway laid into Pro Bowl receiver Demaryius Thomas for skipping the team's offseason program, Manning said he'd love to have his top target on hand but understood his absence.

Thomas is boycotting the Broncos' workouts after being franchise tagged as he angles for a long-term deal instead.

''Certainly, you always like for everybody to be here during this time, but you know D.T.'s got a personal issue and I want it to work out the best for him,'' Manning said. ''He's my teammate, but he's my friend, as well, and this is that business side of it that comes into play. And I'm pulling for it to work out the best for him.''

There are concerns a prolonged boycott by Thomas could hinder the installation of Kubiak's offense, which will feature Manning's tactical and timing proficiencies while placing a greater emphasis on the run and two-tight end sets.

Elway has said this new offense will save Manning's arm, and Kubiak has suggested he might manage Manning's health by giving him some breaks in the fourth quarter, getting backup Brock Osweiler on the field more.

That's another matter Manning declined to discuss.

''We've got a 1 o'clock lift, it's going to be pretty exciting, and then we've got a 2 o'clock meeting,'' Manning said. ''So, I'm trying to kind of focus in here on the now. So, whatever they feel is best, I guess I'll follow suit. But I feel good and obviously I enjoy being out there.''

Kubiak said working with Manning is everything he thought it would be - and awfully challenging.

''He wants to know `Why?' Great players ask, `Why?''' Kubiak said. ''I think I told the team that this morning. I know for however many years I was here as (Mike) Shanahan's coordinator, Shannon Sharpe sat in the front row and John (Elway) sat right next to Shannon. Believe me, they asked, `Why?' a lot. That's what great players do. You better have those answers for them.''

Despite being a student of the game, Manning said he hasn't studied how other 39-year-old quarterbacks fared.

''You can't lump them all into the same category,'' Manning said. ''I think there's young 39s and old 39s. So, I'm in that young group for sure. March birthday.''

He added he wasn't ''interested in talking about how old I am much more after this point.''
