Michigan football has boasted a number of large spreads over the years against rival Michigan State.

This weekend's will be one of the biggest.

In the first betting line released for Saturday's game in East Lansing (noon, ABC/ESPN/ESPN2), the 7-0 Wolverines are 18-point favorites over the 2-5 Spartans.

The line from CG Technology appeared on wagertalk.com.

It matches the futures line from Westgate Las Vegas SuperBook last week, which had U-M giving 18.5 points.

This will be the third-largest spread in the series since at least 1980, following 28 in 1992, 26.5 in 1991 and 18.5 in 1981.
