Broncos offensive coordinator Rich Scangarello comes from the Mike Shanahan coaching tree and he runs an offense with many bootlegs and rollouts. Those kinds of plays work best when the quarterback lines up under center, something Drew Lock rarely did at Missouri.

“I think when you look at what he did in college offensively, he’s in the spread offense and wasn’t under the center very often,” general manager John Elway said on April 26. “With what we’re going to do offensively, he’s going to have a lot of work to do.”

Lock did occasionally line up under center while in college and he did it again at the Senior Bowl in January. He’s confident he’ll be able to make the transition to lining up under center in Denver.

“Under center for me was a little bit more on 10-and-in [during college],” Lock said on April 27. “We used that in the red zone and the tight red. And in the Senior Bowl, I got a lot of that with [Raiders] Coach [Jon] Gruden and that staff there.

“I thought I did an awesome job being able to transition into that. It was a little different, but I think that’s something that if you’ve played quarterback your whole life, you’re an athlete, you should be able to take under-center snaps and be just fine doing that.”

If all goes well in Denver, Joe Flacco will keep Lock on the bench for at least the 2019 season. That would give Lock time to learn the offense and practice lining up under center before being thrust into game action.

The 22-year-old QB is confident he’ll be ready when called upon.
