"He's smart. He's demanding, and he helps out a lot. He's real relaxed. He's not uptight. He's not an angry guy. He's [like], 'Hey, right here,' simple stuff like that."

Just as important in helping the offense work at a crisper pace is the simplification of the offense under coordinator Bill Musgrave.

"It allows us to play faster," running back Devontae Booker said. "The play calls come in quick, and they're not long like they have been in the past.

"Part of the reason is that once you've got a short play-call -- whatever it is -- you can go out there, you already know what you're doing, you can go out there and play fast. When you've got a long play call, it makes you think. Everybody's getting lined up in the wrong places and different stuff."

That wasn't the case Tuesday.

"When the play is called -- and they're pretty short and sweet -- you can go out there and play fast," Booker said. "So it's pretty cool."

The play calls and the relaying of them was so crisp that at times the offense was the first unit out of the huddle and ready to go for the next snap.

"Yeah, everybody's been playing fast. As soon as the play is called in the huddle, you get out there and lined up. Everybody's ready to roll," Booker said. "The defense was pretty slow coming out of their huddle, so we were kind of waiting for them a little bit."

And when the play began, the offense avoided giveaways. One pass was nearly intercepted by Justin Simmons, but Demaryius Thomas snatched it back for the catch. The defense generated pressure, but Keenum, Paxton Lynch and Chad Kelly were all decisive and got rid of the ball quickly, leading to some solid gains through the air.
