Speed is one of the many athletic gifts
Bush was one of the fastest rookies in the 2006 draft. He had a recorded time of 4.38 seconds for the 40-yard dash. That speed, and the overall ability he demonstrated at Southern Cal, is why the Saints drafted him second overall.
Based on available research, Bush had the fastest 40-time of any back in 2006, and it would put him in the top tier of players at all positions in any draft year.
At the age of 28 and preparing to enter his eighth pro season -- first with the Lions -- Bush isn't putting the brakes on his offseason workout program.
In an effort to maintain his speed, Bush does speed drills in Southern California under the tutelage of Maurice Greene, one of the fastest sprinters in history and a combined four-time 100-meter gold medalist in the Olympic Games and World Championships.
Before heading home to California after participating in the mini-camp that ended the Lions' team-supervised offseason workouts, Bush spoke of his motivation for training under Greene.
"I'm just trying to work on my endurance -- getting faster," Bush said. "That's really it. It just comes down to trying to improve on my speed and my running technique and my endurance."
Bush is one many Lions players who participate in structured workout programs that are outside the bounds of the team's official workout program. It is a practice that is encouraged by the team.
"As they go through their careers, they want to refine their talent," said Jason Arapoff, the Lions' long time coordinator of physical development.
"He (Bush) is refining that as he goes along. He's found a guy (Greene) that he likes and trusts.
"I like the concept of a guy having a plan when he leaves here."
Players participate in various programs to sharpen their skills and get ready for training camp. Pilates, weight and speed training, stretching and martial arts are among the many activities players participate in under the supervision of experienced professionals.
Those are just two of many examples of players having a workout plan to supplement football-specific drills they do at a team facility.
In Bush's case, there's fast, and there's super-fast. Greene is super-fast, and videos of the workouts he puts Bush through are grueling.
Greene once ran the 100-meters in a world-best time of 9.79 seconds, and he ran the distance under 10 seconds 53 times.
Bush has never run as far as 100 meters -- or even 100 yards -- from scrimmage on one play in his first seven seasons.
His longest play was an 88-yard TD reception against the Bears in the NFC Championship after the 2006 season.
Bush probably covered more than 100 yards as he weaved his way through the Bears' defense. Before reaching the end zone, Bush pointed at Bears middle linebacker Brian Urlacher, taunting him.
Good thing Bush was too fast for Urlacher to catch him.
