Then, at 9:20 a.m. Monday, the speaker in the southeast corner of the practice field was turned up, and an up-tempo picking of the banjo came through, loud enough to echo off the just-sodded berm and the steel beams of the under-construction indoor facility.
It was "Rocky Top."
And this wasn't the marching-band version that you hear ad infinitum when watching a Tennessee Volunteers game, but the old-school, bluegrass version first made popular by the Osborne Brothers in 1967.
The Broncos could thank
"I’ve seen him dance but I’ve never seen him dance like that," said linebacker
"Oh my God, Peyton!" added defensive tackle
"'Rocky Top,' Rocky Mountain. It's gotta be a Tennessee thing, man. Me playing for the Titans a couple of years, I heard the song a couple of times. I really didn't know he was going to play it today."
"I love it. They need to play it every day," said Jackson, who played there in 2010-11.
"Malik Jackson surprised me by singing the song and knowing the words and everything," Vickerson said.
But even some non-Volunteers enjoyed the selection.
"I like that song because it reminds me of when Wyoming went out to Tennessee and we beat them, 13-7, believe it or not," said defensive tackle
"They played that song in our locker room for a week straight before we went out there so it was just stuck in my head. But yeah Peyton had a nice dance out there. I was trying to mimic him a little bit but I just couldn’t do a good job doing that.”
Manning drew the cameras, but perhaps the best moves belonged to wide receiver
Welker and others will need to have some different moves when teammates like Miller play DJ.
"When it’s my day I think you’ll be asking other guys about what I played and what they thought about what I played," said Miller. "It was Peyton’s day, so it was all good.”
