Von Miller and Co., though, are aiming to make Flacco uncomfortable. When the first-team units faced off on Monday, the defense appeared to gain the upper hand on more than one occasion.

"I felt like I had to slide a little bit at times and get the ball out of my hands," Flacco said. "Guys had to get open quick. Then there were times where it was hit your foot, get the ball out because the guy is open. I thought it was good. We're going to get tested every single day out there. We have a couple of guys on the edge that obviously can play football. Everybody else to go along with that — that's a good defense over there.

"Having experience throughout my career, it's an awesome test and an awesome advantage that we have to be able to go against a good defense, a good scheme and good pass-rushers. Everywhere you look, you have guys that can play. I think that's going to prepare us big time."

Flacco's focus appears set on meeting that challenge — even if it means Lock's tutelage falls on Scangarello instead of him.

That doesn't mean the second-round pick can't learn from Flacco. It just means Lock may spend more time talking with Scangarello and watching Flacco's timing on the field.

"Rich does such a good job in those meeting rooms," Flacco said. "Drew is going to learn from listening to him talk and then us getting the reps on the field and seeing how we all do it as a collective group of quarterbacks. Listen, I hope he does learn from me because that means we're out there and we're slinging it around and having a lot of fun. Because he's going to learn by watching us do it and watching us do it well. That is how he is going to learn the timing and all of those things is to be able to see it on film and hear Rich talk about it with me and digest as much of that as possible.
