Grissom's high school coach, for his part, thinks Oklahoma fans will be "more than pleasantly surprised" with his former pupil's performance at tight end.
"He was a ferocious blocker," Dreiling said. "I think it's a pretty natural move, given his body. He's got incredible hands, and his arms are so long."
"I always felt like he was a natural on offense," Dreiling said. "He's gifted on the offensive side."
