Denver Broncos quarterback Peyton Manning arrived for his first day of the team’s offseason workouts Monday with his comeback 2012 season in the rearview mirror and looking for more in 2013.

“John Elway wants to sort of set a kind of attitude, kind of an edge around here,” Manning said. “Kind of an uncomfortable atmosphere, which I believe in. Last year was good, but it wasn’t great and we’re looking for that great season.”

The Broncos gathered for the first day of their conditioning program Monday, their first team function since they packed up their gear in the locker room the day after their double-overtime loss to the Ravens in the AFC divisional round game. The loss ruined a 13-3 season that saw the Broncos win 11 consecutive games to close out the regular season and earn homefield advantage in the postseason.

Manning said recent workouts at Duke University with Demaryius Thomas, Eric Decker and one of the team’s newest additions in Wes Welker went well and that he felt some additional arm strength in five workouts.

Manning earned the league’s comeback player of the year award last season after missing 2011 with multiple neck surgeries.

I’ve made some improvements since last year, but still have a plan with the trainers, a plan with the strength coaches,” Manning said. “I’m still in a get stronger, rehab mode. I’ll be that way for a pretty good while.”

Manning also said he hopes long-time teammate and friend Brandon Stokley will be re-signed by the Broncos. Welker’s signing fills the role Stokley played in the offense last season.

“Hope it’s not necessarily a close-door discussion,” Manning said. “In a perfect world I’d like both of them to be on the team this year.”
