The most scrutinized quarterback on the planet is taking part in minicamp with his new team and estimates that he has not yet fully recovered from multiple surgical procedures on his neck.

“I can’t emphasize enough that I still have rehab to do,” Peyton Manning told USA Today on Tuesday. “That's still part of the process.”

Manning missed all of the 2011 season and underwent fusion of cervical vertebrae last September. Since then, his arm strength has been steadily — and slowly, to Manning’s way of thinking — returning.

“I had the physical with the doctors Monday,” Manning said, “and we're doing all the right things, but some things take time.”

Manning is unconcerned about taking a hit when the season opens Sept. 9. “I don't worry about it,” Manning said. “It hasn't even crossed my mind. I've never taken it for granted being able to play. Then, sitting out last year, I never felt sorry for myself because I had 20 years of unbelievable health going up to that point. ... Last year I tried to handle it with a good attitude. But it's nice to be back on the field with a different team, different teammates, it's exciting to do that.”

Tom Moore, Manning’s former offensive coordinator in Indianapolis, visited the Broncos’ minicamp at the invitation of Coach John Fox and liked what he saw from Manning. “He looks great,” Moore said (via the Denver Post). “He looks like what I saw every day. He looks great, just great. There's nobody like him.”
