HIGHLANDS RANCH, Colo. -- Few people know the ins and outs of what the Broncos' offensive linemen face this summer better than Chris Kuper.
A 2006 sixth-round draft pick who eventually became one of the league's best guards, Kuper played eight seasons for the Broncos, including four with current Offensive Coordinator Rick Dennison as his position coach and one with Clancy Barone, the current offensive-line coach, on the job. He understands a zone-blocking-based scheme based on his first three years when Mike Shanahan was still the head coach, and other concepts that followed from 2009 onward until injuries forced his retirement after the 2013 season.
