ENGLEWOOD, Colo. -- The play of quarterback Case Keenum is the most visible reason why the offense has shown improved consistency and form during the first five days of training camp.

But the cohesion and progress of the offensive line can't be overlooked, either.

Since getting left guard Ron Leary and right tackle Jared Veldheer back for the start of training camp to fill out the first-team quintet, the Broncos' line has gradually begun to take on its projected form -- and has helped blast open holes for all five of their running backs.

"I like that way that first group looks when they're in there," Offensive Coordinator Bill Musgrave said.

Leary's leadership and guidance is one of the causes of their early success -- particularly his left-side collaboration with tackle Garett Bolles. During Wednesday's practice, Leary saw evidence that their collaboration could pay long-term dividends.

"[The defense] ran a lot of twists on us today, and I think we picked every single one of them up," Leary said. "If you know O-line play, you know that's real big -- especially for two new guys playing next to each other. So that was a big step we took today."

But gaining cohesion is about more than what happens in practice and during games. Bonding away from the field is crucial to that process. Leary focused on bringing the group together for social gatherings and extra work, having seen during his seasons with the Dallas Cowboys how these activities could lead to on-field success.

"In Dallas, we were inseparable. We did everything together -- whether it was right or wrong. You know, if it was wrong, we all did it together," he said, smiling. "So that's what I'm trying to get here -- [to] just get five guys, or however many it is, guys that care for each other, that love each other, that love the game of ball and love being physical, and just want to be great, [and] put all the individual stuff aside.
