Titans Johnson gets 2Y yards & considers race vs Usain Bolt
 

Johnson became the sixth player in NFL history to rush for 2,000 yards in a season, then scored the go-ahead touchdown on a 1-yard run with 4:33 remaining to send Tennessee to a 17-13 victory over the Seattle Seahawks in the season finale Sunday.

Sources close to the situation told ESPN NFL Insider Adam Schefter that representatives for the Titans running back and Olympic champion Usain Bolt of Jamaica have spent recent days trying to set up a race between the two men to determine who really is the world's fastest human.
The race would be used to raise money for charity.

Bolt would smoke him, and so would most world class sprinters....doesn't look like it's going to happen at all though.

Actually I don't think Johnson is the fastest player in the NFL: for example the Chiefs & former UT back Jamaal Charles won the Big 12 100 meter sprint championship one year with a time of 10.2, a time I don't think Johnson ever matched ?
