Lou Holtz resigned as Minnesota's football coach in late November 1985 to take the job at Notre Dame. Jim Dutcher resigned as Minnesota's men's basketball coach in late January 1986 when the administration decided to forfeit a game in the wake of rape allegations against three players who were later acquitted.
The four coaches that followed Holtz over the next quarter-century were John Gutekunst, Jim Wacker, Glen Mason and Tim Brewster. All were fired.
The three coaches that followed Dutcher were Clem Haskins, Dan Monson and Tubby Smith. All were fired.
This doesn't include the interims: Jimmy Williams in 1986 and Jim Molinari in 2006-07 in basketball, and Jeff Horton in 2010 in football.
Haskins lasted 13 seasons and was successful by Minnesota standards, before being run off by accusations of academic mischief. Mason lasted 10 seasons and was above-average by Minnesota standards, before succumbing to an administration that wanted a salesman and recruiting ace in charge.
The others were fired for failing to win: Gutekunst, Wacker, Brewster (the alleged recruiting ace), Monson and now Smith.
What we have learned in the 27-plus years since Holtz and Dutcher left is that you didn't come to Minnesota for one of these high-profile tasks and then either move to a better job or leave coaching at your volition.
You came to Minnesota, instead, to have your coaching career die on the vine.
