Mason Cole never was a running back or anything, not at any level. But there the rookie center was on David Johnson's 30-yard screen pass Sunday against the Seahawks, out front of the running back, looking like Usain Bolt. (OK, maybe you'd have to squint a little to see the comparison, but you get the idea.)

"It must be adrenaline or something," Cole said. "You're playing the game just trying to make a play, make something happen, so you just do it."

It wasn't as much that Cole sprinted some 35 yards as much as when he sprinted -- it was the fourth quarter during a long game. But there Cole was, putting on the afterburners to get a chuck in on linebacker Bobby Wagner near the end of the play. Growing up in Florida, while Cole never was a running back, he did play lacrosse -- which featured plenty of running.

That ended when he got to high school. He couldn't keep playing in large part because of high school spring football and scheduling conflicts. But, oh by the way, it was "way too much running."

He'll stick with his confined spaces of an offensive lineman these days, ready for the on-occasion dash down the field like Sunday.

"I'm good with one or two (sprints)," Cole said.
