Mark Parson is the exactly the kind of undersized underdog that shows like HBO’s “Hard Knocks” want to cover.
The 5-foot-9 cornerback went undrafted out of Ohio University in 2009 before getting a couple of training camp shots with the New Orleans Saints and Houston Texans, and later with the Edmonton Eskimos of the Canadian Football League. While those opportunities didn’t lead to a regular-season roster spot, Parson has stayed in the game as a trainer and speed coach.
In this video, Parson displays the “DB route tree” drill that he learned at Deion Sanders‘ Prime U. In addition to being a good conditioning workout, this drill also reinforces the right techniques and angles for covering the routes most commonly run by receivers.
