Reuter: Mock Draft 9.0
"He presents a threat that we really haven't seen before," Polian said of the Baylor quarterback's arm and sprinter's speed.
Often compared to last year's top pick, dual-threat QB Cam Newton, Polian contrasted their two styles of play.
Griffin "is a world-class track man and as such, is a bit of a long-strider and a bit of a narrow-base guy, as opposed to Cam, who's an instinctive, natural football runner," Polian said.
"RG3 is not that," Polian added. "That said, he has enough shake to beat most defensive linemen. And once he sticks his foot in the ground and goes, it's gone baby, gone ... that's unique. He presents a threat that's absolutely unique."
Polian also lauded the 6-foot-3, 223-pound Griffin's arm: "If he pulls up to throw ... all he has to do is stand up and flick that wrist and the ball will go across the field 55, 50 yards in the wink of an eye -- on a rope, and it's accurate."
"He can throw the ball pretty well, and he's fast," Miller said. "But if you hit him enough times, he's going to wear down. He can run and throw, but I wouldn't put him in that same class as (Michael) Vick, Cam (Newton) or (Josh) Freeman," Miller said.
