"You turn the film on and they throw screen on the other side of the field away from him and he freaking sticks his foot in the ground and runs over there and is in on the tackle for about a five or six-yard gain to a skill guy," Legg said. "That's the kind of talent this guy has."
While the Herd hasn't seen a defensive line as big as Purdue's, the Boilermakers haven't seen an offense as prolific as Marshall's. The Herd has run more plays from scrimmage than any other team in the FBS (371) and is a well-known passing team, ranked No. 1 at 383.5 yards per game behind quarterback Rakeem Cato. But it showed it could run as well, gaining 334 yards on the ground against Rice.
Marshall Coach Doc Holliday said quickness remains the offense's strength - how fast they can run a play and how fast the players are once the ball is in their hands.
That should be able to counteract Purdue's defensive size advantage.
"We can do a lot of things with our offense that we don't need to block the front guys as long," Holliday said. "We have some things in our offense now that can allow Cato to get the ball out of his hands quick. We have the ability to run the ball if they give it to us. We have the screen game to where we don't have to block those guys as long."
Marshall's players are excited to line up against a Big Ten team like Purdue, to get the chance to face an opponent from a BCS automatic qualifying conference.
The Herd knows what a win against a foe like that can do for a team's psyche. They experienced it when they won last year at Louisville.
"Anytime you go into another team's arena, especially a team like that, and come out with a win, it'll definitely get guys' confidence up and have them feeling better about themselves and carrying that energy into the next game," defensive end Jeremiah Taylor said. "I think a big win would definitely help us out."
