Pierre Garcon has been challenged to a race by Robert Griffin III.

Garcon believes Griffin isn't as fast as he was last season.

"Robert obviously can't run as fast as he did last year because of his knee brace and his knee," Garcon told ESPN980 radio. "But it's the same offense, to be honest with you. It's nothing different. It hasn't changed at all." 

"There's no knee issue," Griffin said. "I love my receiver. If he wants to race, then we can race."
