Peyton Manning is still getting accustomed to the Denver Broncos' new offense under Gary Kubiak.

Manning has been more comfortable operating from the shotgun late in his career, but he's coming up to the line of scrimmage on almost all of his snaps right now.

"We know the other end of the stick is fine. It's something he's been doing forever," Kubiak said. "So, we're going to spend a lot of time under center initially. ... He's been very responsive and he's working extremely hard."

After what he called the Broncos' "first real day of practice in shoulder pads," Manning said he's eager to smooth out the roughness in this new hybrid offense, saying, "I feel I can do whatever they ask me to do."

Some believe quarterbacks like the shotgun because they don't have to take their eyes off the pass rush.
