Jim Harbaugh is due a pay raise this week, while two of his top assistants are in line for six-figure retention bonuses. Thursday marks the day Harbaugh, who enters his fourth year as head football coach at Michigan, is due a 10 percent boost to his yearly compensation. According to the terms of his contract, Harbaugh will earn a 10 percent raise on his $500,000-a-year salary, and, more lucratively, a 10 percent raise on his $4.5 million in additional compensation (media obligations, public appearances, etc.) That means Harbaugh -- who signed a seven-year contract in December 2014 that paid him $5 million a year over the first two years -- is set to make $5.5 million in 2018. Additionally, Harbaugh is also eligible to draw from a $2 million-a-year life insurance policy, a compensation addendum that was tacked onto his contract in 2016. Michigan is coming off an 8-5 season in 2017 that saw it finish the season on a three-game losing streak, including a 26-19 collapse against South Carolina in the Outback Bowl.
