Michigan has extended John Beilein's contract another two years, and giving him a million dollar a year raise. The 62-year-old Beilein is entering his ninth season at Michigan. He has led the Wolverines to two Big Ten titles.   Michigan says Beilein's annual compensation will increase to $3.37 million, including $1.5 million in separate deferred payments.  He’ll be under contract through 2021. Two years ago, following the Wolverines' Final Four run, Michigan extended Beilein's deal through 2018-19, giving him $2.45 million a year in total compensation. The 25th-ranked Wolverines open the season next week against Northern Michigan.
