For the past eight years, sprinter and five time gold medalist Michael Johnson has shown former college football players how to impress scouts at the NFL combine. His workout facility at Craig Ranch in McKinney is simply known as the Michael Johnson Performance Center.

"It’s a matter of trying to get these guys to be consistent," said Johnson. "If they do that, when they get to the combine, they'll have their best performance."

While Johnson has been training and guiding former college football players, this is the first time that he has been able to utilize his new center in McKinney. The NFL combine will take place Feb. 20th through Feb. 26th in Indianapolis where speed is the name of the game. They need to learn how to get off the line

better in the 40-yard dash so they can turn in their best time.

"We have to reteach guys how to run because they've been running the same way for years," said Johnson. "A lot of times, they're running with a ball, they're running with pads on, but a lot of is just inefficiency."

Among his prize students leading up to the combine is Arkansas' Darren McFadden, twice a runner-up to the Heisman Trophy voting and a two-time winner of the Doak Walker Award.

"I'm a very explosive person, but the way they tell me, I can always get more explosive," said McFadden. "By them showing me on a computer, I can actually look at what I’m doing."

Lance Walker, the Director of Performance and Sports Medicine for Michael Johnson Performance said, "McFadden's got so much power, like a real powerful boat. If you don't trim the motor just right, it'll just porpoise right out of the water. He’s got all this power we've got to harness."

Johnson knows all use a different running style, but it allowed him to win five Olympic gold medals. "I got criticized early on in my career for the style that I ran with," Johnson said. "Obviously, it worked. But we decided, 'Hey, we'll take a look at it and see.' "

The players he's coaching this week are on the verge of starting a career in professional football, and Johnson is trying to give them a physical and mental edge.

"I've learned that I can get a lot more flexible and a lot faster," said Derek Lokey, who starred at Texas as a defensive tackle. "Here, I've learned a lot about myself and also learned a lot of mental tricks."

"This is my job now. I love it," said Tony Hills, a former teammate with Lokey at Texas. "For all the kids out there, education is important. But I tell you what, it’s a lot easier just to play football."

Johnson has his trainees working six to eight hours a day, six days a week. No one said preparing to face NFL scouts would be easy, but he’s determined to have his group of NFL hopefuls ready for the combine.
