NIT has 32 teams. 12 invites to the top two in six conferences not going to the tourney. Gophers aren't in those two from the big 10
then 20 invites to the best 20 in the NET. Guessing that would get to the mid 80s in NET. Gophers are 88.
quick math has me thinking to 86 (currently PSU). needed to win one more game
add: did find one bracket estimate with the Gophers in it - playing New Mexico

The at-large teams are not picked straight off the NET rankings. A committee will consider resumes and invite the 20 at-large NIT teams based on the resumes, just as happens for the NCAA Tourney.
So, #88 could get them in (I think probably will).
