Patriots Rumors: 4 replacements for Bill Belichick

4. Jim Harbaugh, Head Coach, Michigan

For a couple of years now, Jim Harbaugh's name has come up each offseason as one we could see make a return to the NFL. Harbaugh has had incredible success at Michigan since he left the league to take over the job with his Wolverines. To this day, Harbaugh is 82-25 with Michigan and has guided the program to consecutive College Football Playoff appearances along with several high profile bowl games.

This definitely seems like the type of gig Harbaugh would go for. He's been a longtime, respected head coach both at the pro and college level. This would be the type of opportunity that could get him to ditch the college ranks to return to the NFL.

It is likely that the Patriots need a total overhaul within their coaching staff, should Belichick end up being let go. Harbaugh is well-connected and would have no problem bringing in one of the best staffs he could possibly put together.

Which of these make the most sense for New England? They're all high-profile candidates and each bring their own positives to the table.
