Broncos rookie running back Montee Ball says his head was spinning the first time he stepped on a practice field with Peyton Manning.

“Well, first off, it was overwhelming at the beginning just because it’s a difficult offensive play book, just because it’s Peyton Manning. He keeps a lot of players on his toes by changing the plays and all that stuff,” Ball said. “In our OTAs and that stuff. Every day at practice we would work on something. He would ask me, ‘What do you think you need help in?’ I would tell him I need help with this route or this play. Then we would work on it right after practice before we even go to our meetings.

Ball said Manning has a knack for seeing where the Broncos can have success in the running game, and Manning tells Ball where he can beat an opposing defense.

“That’s another way he has helped me out, really understanding what the defense is trying to accomplish and what they are trying to disguise,” Ball said. “In film and during meetings he really preached to me about watching the safeties and all that stuff. It really helped me out overall with my routes, with my runs and all that stuff.”

In college at Wisconsin, Ball was the focal point of a simple run-first offense. It’s not like that in Denver.
