With the start of the NFL Scouting Combine on Tuesday, prospects will have another opportunity to break running back Chris Johnson's 40-yard-dash record of 4.24 seconds.
Tuesday on SiriusXM NFL Radio (via ESPN.com), Johnson spoke about the record and the possibility of it falling this year.
"I didn't think it would hold on this long," Johnson said. "To be honest, I don't want to see the record go. But if somebody does break it...I'll be happy for them and give them a handshake and congratulate them."
Johnson set the record in 2008 as a prospect coming out of East Carolina, which helped him get drafted 24th overall by the Tennessee Titans.
Per ESPN.com, New York Jets running back Dri Archer came closest to breaking the mark in 2014, when he ran a 4.26 40. NFL Network's Daniel Jeremiah took a look at who might challenge Johnson this season:
There will be extra incentive for the prospects to break the 4.24-second barrier. Adidas will give $1 million to the player who breaks Johnson's record while wearing its shoes, per ESPN.com.
"I wish they had that when I was coming out," Johnson said. "They'll be more proud of getting the million dollars than getting a handshake, you know it is what is."
Johnson has done well for himself even though he wasn't paid for his historic showing eight years ago. He rushed for over 1,000 yards in each of his first six seasons, including 2,006 yards in 2009. He's one of seven players in NFL history to rush for over 2,000 yards.
While he didn't give any pointers on how to rush for that many yards in the NFL, he did give some advice for players preparing for the dash this week.
"Run fast," Johnson said.
If one of these players does break Johnson's record, then he will likely see his draft stock rise substantially before the April selection process.
