He works with athletes on strength and speed and agility. Last summer, a bunch of NFL players worked out at Plex while they waited for the lockout to end. Wednesday, a bunch of NFL hopefuls worked out there preparing for the NFL Combine. Chances are you have heard of two. Kirkpatrick was an All-American cornerback at Alabama. Keenum set all the big NCAA career passing records at Houston. In the world of college football, they are both stars. But in the world of professional football, Kirkpatrick is the guy who has everything and Keenum is the guy trying to prove he has something.
