Despite the success of its defense, Michigan State was averaging less than two sacks per game entering Saturday.
That changed as the Spartans racked up a season-high five sacks in their 14-0 win against Purdue.
"It helps when you're up to put pressure on the quarterback because you expect a little more pass than run," defensive coordinator Pat Narduzzi said. "We did a good job of executing and putting pressure on the quarterback."
The defensive line led the charge with 3.5 sacks of Purdue freshman quarterback Danny Etling.
"We had four sacks as a defensive line," Calhoun said. "Just as a defensive line and you could tell he was scrambling through the pocket. He's a great quarterback and he was scrambling through the pocket and he was trying to make plays.
"I feel like the pressure that we had disrupted him a little bit, and it kind of warned him as the game went on."
"Denzel Drone had a great sack coming off the edge for what I believe is his first of the year," Narduzzi said. "He had me jumping in the box."
