Jim Harbaugh is all about gamesmanship. As Michigan's coach, he's become notorious for not announcing starting quarterbacks and even ceasing the practice of releasing and exchanging depth charts during game week.

If you check Michigan's football roster, you'll see it hasn't been updated since the 2016 season. There is no rule saying schools have to update their roster, but we're used to seeing schools do a full update in July prior to media days, if not earlier in the year to reflect updates for spring practice.

NJ.com -- specifically NJ Advance Media -- contacted Michigan in an effort for an updated roster for a feature on New Jersey players in the Big Ten. Michigan responded that a 2017 roster won't be posted "until the first game week."
