Jon Gruden, Super Bowl winning head coach and current ESPN NFL analyst, didn't sugarcoat it when asked about what he thought of Urban Meyer's run this season at Ohio State.

"Urban Meyer did the greatest coaching job of all time," Gruden said Thursday on Colin Cowherd's radio show, The Herd. "Winning a national championship with his third-string quarterback, I've never seen that before."

Gruden, of course, was referring to Cardale Jones guiding the Buckeyes to three-straight wins en route to their national championship. That included a 42-20 rout of Oregon in the first-ever College Football Playoff national title game.

"What he did at Ohio State, losing a Heisman Trophy candidate and then doing what he did with two different quarterbacks that were backups," Gruden said. "Amazing to me."

High praise from one of the game's better coaches.
