I’m of the opinion that the Gophers are absolutely safe. There are at least 8 teams behind them who are in more danger of missing out on a bid due to a shrinking bubble. All 8 of those teams would have to outplay the Gophers in the next few days and at least 2 of them will lose because of games played against another bubble team.
And even if the remaining 6 all win 2 or 3 games to move themselves ahead of Minnesota, then 2 more teams would have to come from “out” to “in” and bump the Gophers out.
