Watch: Dabo Swinney hilariously coached Jon Gruden down the hill at Clemson

One of the great pregame traditions of Clemson football is apparently a bit tougher than it looks. Clemson players take the field at Clemson Memorial Stadium by first touching Howard's Rock, named for former coach Frank Howard, who said that only players who give 110 percent could touch it. That's followed by the run down the hill behind the east end zone onto the field.
