Elam was then asked how to stop Johnson and he said, via the Detroit Free Press, "I just said he's unstoppable, which means you can't stop him."

"He's pretty old, so I don't know how physical he'll be," Elam said "He's a big guy, but he's older. I guess when they get older they're not going to be as physical, you know what I'm saying? We're going to have to be physical, make him uncomfortable."
