Handicapping the Big Ten race comes down to this: Purdue, Michigan State, everybody else.

The Boilermakers, with reigning national player of the year Zach Edey and his strong supporting cast, are the prohibitive favorites to win a second straight regular-season championship. Michigan State is a possible challenger.

“I think other than maybe Purdue, because of Zach, you could probably throw them all in a hat and pull them out and say, ‘Hey, they could finish here’ and not be shocked,” Illinois coach Brad Underwood said.

Purdue, unranked in the preseason a year ago, enters this season No. 3 and followed by No. 4 Michigan State. The Big Ten’s only other ranked team is No. 25 Illinois. The Big Ten hasn’t had so few teams in the preseason Top 25 since 2018-19.

Michigan State coach Tom Izzo said player movement through the transfer portal makes it difficult to predict how a team will come together.

“I think you’re going to find this league is so much better than what I’ve seen in preseason rankings,” Izzo said.

The Big Ten traditionally has older players, and that’s been accentuated because of the NCAA pandemic policy that allows athletes to have a sixth year of eligibility. The Boilermakers and Spartans have six players who are in their fourth or fifth seasons.

“We have maybe the biggest age discrepancy ever — 23-, 24-year-olds playing against 17-, 18-year-olds sometimes,” Illinois coach Brad Underwood said. “Last year I think it played out a little bit that we saw some very old teams be very successful. We had one of those in our league, Penn State. I think that can be something that separates.”

TOP FRESHMEN

F Mackenzie Mgbako, Indiana, 6-8, 217: Ranked as high as the No. 8 national recruit, he gives the Hoosiers the top freshman for the second straight year. The Gladstone, New Jersey, native was arrested on suspicion of criminal trespass and resisting law enforcement in connection with an incident at a Bloomington restaurant early Sunday.

ON THE COACHING FRONT

Micah Shrewsberry parlayed Penn State’s 23-win season and first NCAA Tournament since 2011 into the job to Notre Dame.

Enter Mike Rhoades, who led VCU to 27 wins, the Atlantic 10 regular-season and tournament titles and the Rams’ third NCAA appearance in six years. Rhoads also had a successful three-year run at Rice.

The Pennsylvania native has a strong track record as a recruiter and is basically starting over with the Lions. He brought A-10 player of the year Ace Baldwin Jr. and Nick Kern with him from VCU and signed seven other transfers.

GAVITT TIPOFF GAMES

ESPN’s exclusion from the conference’s new television contract caused the demise of the ACC/Big Ten Challenge after 24 years.

That leaves the Gavitt Tipoff Games as the Big Ten’s premier early season event. Eight games against Big East opponents will be played in mid-November. All games will be televised on FS1. The annual series honors Gavitt, who founded the Big East.

Nov. 13: Xavier at Purdue; Michigan vs. St. John’s, at Madison Square Garden.

Nov. 14: Wisconsin at Providence; Marquette at Illinois; Iowa at Creighton.

Nov. 15: Georgetown at Rutgers.

Nov. 17: Maryland at Villanova; Butler at Michigan State.
