FRISCO, Texas -- As he attempted to talk through what he expected of the rookie offensive linemen, Marc Colombo finally got into a three-point stance and fired off a few quick steps to demonstrate the drill.
Colombo, 40, last played in an NFL game in 2011, but it is sometimes hard to get the player out of the Dallas Cowboys' offensive line coach. Colombo played in 111 games in his career, starting 95 with 72 starts coming as the Cowboys' right tackle from 2006 through 2010.
"Playing experience helps me a ton, just being able to demonstrate the drills and getting the guys to do the technique exactly the way it's being taught is huge," Colombo said.
