Jim Harbaugh and his players say they often see their new-look offense clicking behind closed doors, taking advantage of speed in space.

No. 16 Michigan (4-1, 2-1 Big Ten) is hoping to carry over success with the ball into games when everyone is watching.

Illinois (2-3, 0-2) may be very accommodating.

The Fighting Illini haven’t put up much resistance during their three-game losing streak, giving up nearly 39 points per game to Eastern Michigan, Nebraska and Minnesota.

The Wolverines have a shot to put together a feel-good performance as they did in a 52-0 win over Rutgers two weeks ago. Michigan may need a boost of confidence, coming off a 10-3 victory against Iowa in which it was held scoreless over the last three quarters.

During games, big plays have been rare on the ground and through the air.

“You see it in practice all the time,” offensive tackle Jon Runyan said. “I’m not worried about it.”

Harbaugh insists first-year offensive coordinator Josh Gattis has the unit hitting its stride and players seem to believe the same.

“The sky really is the limit for this offense,” quarterback Shea Patterson said. “It’s just a matter of time.”
