Good grief, most of us know this UM history by now—but if you don't and want to thread-start, look it up:
Jimmy went 8-5 and opened his career with a takedown of #1 Auburn in the Kickoff Classic, beat #17 Florida the next week and then fell at #14 Michigan and home against #15 Florida State weeks later. Won five in a row and was 8-2 before the wheels fell off with a few pretty iconic losses; Maryland (blew a a 31-0 halftime lead, lost 42-40), Boston College (Hail Flutie) and wrong side of a Fiesta Bowl shootout against UCLA.
Would've backdoored into a title year two, winning out after losing to Florida in the opener—but #2 Miami was throttled 35-7 by #8 Tennessee in the Sugar Bowl. Oklahoma won the title (who Miami beat during the regular season, by beating undefeated Penn State in the Orange Bowl.)
Lost the title game in year three, as well—1986—with the infamous Fiesta Bowl debacle against Penn State. Finally won it all year four, took the Dallas job after the 1988 season—his final words to his one-loss Canes, "Beat Notre Dame" as the refs stole a shot at another title with a bogus call in South Bend during the season.
What any of this has to do with Mario Cristobal's legacy at Miami is nil, but at least now you know JJ's history at UM.
