Michigan has tried the breaking the bank route already.
Honestly, Harbaugh was as good a bet as anyone, particularly if you were going to spend big money.
So if that didn't work, what now?
Presumably you go through a normal coach hiring process where you look at the best folks coming up right now, rather than trying to poach someone with as much money as can be scrimped together. Because unless you think you can get Saban or Sweeney, there really isn't any point in breaking any more banks.
BUT, it's 2020, so does this season even count? Maybe Harbaugh gets a pass on that basis alone.
