ENGLEWOOD, Colo. (AP) Peyton Manning seems to be having a lot more fun this summer.
He's still grinding through training camp like always but he's also showing a loosey-goosey side that he rarely flashed in Indy or in his first two seasons in Denver.
One morning, he's doing a dorky dance to ''Rocky Top'' during stretch time at Broncos headquarters - dancing like nobody's watching even though he knows everybody is.
Another day he's taking snaps from Brandon Stokley's 10-year-old boy on the side during special teams drills.
Or letting his twin toddlers tackle him after a practice at Sports Authority Field.
