Caleb TerBush will do his best Denard Robinson impression this week.
And it won't be nearly as good as the real thing.
But Purdue doesn't have anyone on the roster who can mimic what Michigan's dynamic quarterback Robinson can do.
TerBush is academically ineligible but has been the scout team quarterback for much of the season, coach Danny Hope said.
When asked who would be the best person to portray Robinson in looks for the defense this week, defensive end Ryan Kerrigan said Rob Henry because Henry is the team's fastest player. Henry isn't an option, obviously, because of an injury. And even if he was healthy, he'd be working with the No. 1 offense. But Kerrigan's point was made: It'll be tough to simulate Robinson's speed.
Typically against dual-threat quarterbacks, Purdue will employ one defensive player as a "spy." That's been safety Albert Evans at points, though Hope said it could be a different player.
Not that Hope would give any of his defensive game plan away.
"Sometimes (having a spy) spreads you thin in some other spots," he said. "You have a lot of zones and areas that you have to cover, so that can spread you thin in some spots. But certain down and distance against certain groupings in formations, if they're a team with the quarterback that likes to take the ball and run with it a lot, at times, we have to assign a guy to spy him."
