Some key matchups in the Big Ten are about to begin in earnest this week.

Starting with No. 16 Michigan (5-1) visiting No. 7 Penn State (6-0). Then next week it’s Wisconsin at Ohio State, both currently unbeaten.

As of this writing, Penn State was a nine-point favorite over Michigan. The opening line was eight.

That opening line really surprised me.

To date, the two teams have only played one common opponent in Iowa. Michigan beat Iowa 10-3 in Ann Arbor, and visiting Penn State nipped the Hawkeyes 17-12.

That would make the Wolverines a two-point favorite, if excluding home field advantage.

But you can’t eliminate home field advantage, especially when the national Saturday night TV game is in Happy Valley, where over 100,000 screaming home fans will participate in another “White Out.”

Personally, I feel Penn State is somewhat overrated at this juncture in the season. It’s not the same outfit that drubbed visiting Michigan 42-13 in 2017. McSorley and Barkley are now in the NFL.

The Nittany Lion defense is rated No. 4 in the nation, and like Michigan, its offense hasn’t done much against quality opponents. Both teams have easily scored against bottom-feeder foes.

Make it: Penn State 24, Michigan 20

According to ESPN’s College Football Power Index, Michigan only has a 21.4 percent chance of winning this game. But it’s going to be a lot closer than Las Vegas oddsmakers think.

Top high school game

Lakeshore 20, Kal. Central 13

The Lancers’ backs are again up against the wall in order to keep their playoff hopes alive.

Lakeshore has made the playoffs 21 straight years, one of the longest consecutive playoff streaks in the state. Two more wins and the Lancers could be in again. There will be a ton of five-win teams needed to fill out the entire playoff field.
