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.

Leary's leadership and guidance is one of the causes of their early success -- particularly his left-side collaboration with tackle Garettdifficult for station group owners such as Fox and Nexstar if they’re looking to bulk up. Pallone, in particular, has been "very forceful about broadcast ownership," said Andrew Schwartzman, a senior counselor at the Institute for Public Representation at Georgetown University Law Center.
