CHAMPAIGN, Ill. – Illinois offensive coordinator Bill Cubit has a word to describe Michigan State's defense. He says the Spartans are relentless.
Statistically, there's another way to describe them. They're No. 1.
The Spartans (6-1, 3-0 Big Ten) have to the top-rated overall defense in the country.
On Saturday in Champaign they'll meet one of the conference's better offensive teams. Illinois (3-3, 0-2) is scoring 35.3 points a game.
The rest of the game, though, will pit one of the conference's more limited offenses against one of its weakest defenses.
Michigan State scored just one offensive touchdown last week against struggling Purdue. And Illinois' defense gives up 454 yards a game. That's among the Big Ten's weakest.
