In theory, yes. Beat Penn State and Rutgers to finish the season at 15-12 (8-12). Wins vs 3 of the top 4 teams in the conference. Perfect non-conference schedule. But still likely just outside the cutline.
It comes down to the following:
Will Robbins be coming back this week? He was the key to most big wins we've had this year; Iowa, OSU, Mich, etc. He was Big Ten player of the week several times this year for crying out loud. His importance can't be ignored.
In the Gophers' five victories over ranked opponents this season, Robbins averaged 19 points, nine rebounds and 3½ blocks, including vs. Michigan, Ohio State and Iowa.
If Robbins doesn't come back: No chance
BUT...
If Robbins were to come back and we won @PSU (quad 1 possibly) and RUTG (Which they would have good chance at winning). putting them at 15-12.
Then you get to the Big Ten Tournament. Because of how bad they've been without Robbins and Kalscheur, they slipped to the bottom 4 in conference. That could give them a bonus game in the Big Ten tournament (neutral site games are important for resume regardless of opponent)
Say they play Nebraska again and win that, now they are 16-12. They then would play a Wisconsin or a Purdue level team (would be a Quad 1). Adds to the list of quality wins the Gophers already have.
That gets them to 17-12 with a matchup against a possible top 10 opponent (one they've already beat unless it's Illinois).
Even if they didn't win that, and go to 17-13, they would still have just won 4 of 5 games, 1 road and 2 neutral site games. Committee looks at whole body of work and the Gophers have the quality wins that are unmatched with other bubble teams, and Kalshcheur is expected to be back by tourney time. They see a fully healthy Gopher team turn a corner down the stretch and let them into the dance through the back door.
TL/DR; Thre is still a chance.
(( not saying I think this will actually happen. Just a thought. ))
