I believe they will both end up at UND, just as you believe they both will end up at Wisconsin. Looking at the "dumpster fire", if you want to call it that, of an elite hockey program at Wisconsin. Mike Eaves could be fired at the end of the season which could effect committed recruits or even potential recruits. If I'm not mistaken you even said that you can't see Eaves being the head coach next season, which I agree with and it also sounds like most of the fans want him gone too. Wisconsin is 2-18-4 on the season the only team in Division 1 without a conference win and the least amount of wins on the year.
Wisconsin had Boeser decommit during the season had Ford leave the team at the break and there was another committed player that was thinking for decommitting. That can't be a positive sign to Jost or Fabbro to want to play at Wisconsin.
Jost will end up at UND. For Fabbro it will come down to UND and Denver.
