I don't agree with the OP, but this brings up an interesting question...What are the best seasons we remember?
For me, I'm in the camp that doesn't care about the vacated stuff...Those seasons happened and my memories are real. I don't reduce those seasons at all.
1)1997 - Final 4, epic Big Ten run. Great players and memories. Beating IU in Bloomington in OT when we trailed by 9 with less than a minute to go. Rolling thru the Big Ten at 16-2. Beating Clemson and UCLA. Terrible charge call on Courtney James stopped us vs Kentucky. Kentucky also got 4 or 5 other 50/50 calls before that charge and that's really why Clem went off. They got beneficial calls all night. We blew a ton of layups..Eric Harris, Tarver and John Thomas. Also, Quincy had a terrible night. Something like 1-9. I think we beat Kentucky 8 out of 10 times if we get a fair shake from the refs and if we don't shoot like crap. I guess we played nervous.
2)1982 - Big Ten Title, lost in sweet 16 to Denny Crum's Louisville team. Had an terrific performance vs OSU in the Barn to clinch the title. Both teams shot well and we won by about 10 points, 90-80 as I recall. A little disappointing how we played vs LV. Randy Brewer got in foul trouble...Had some great role players like Cookie Holmes, Zebedee Howell and Daryl Mitchell who was Mr. Clutch all season. Mark Hall and Tommy Davis had some huge games as well. Trent was the star, but it was very much a team effort. As I recall, we struggled to shoot the ball in that LV game and were playing from 4 to 8 points down most of the game.
3)1990 - Elite 8 run. Kind of disappointing Big Ten season as they finished 5th I believe. But they really came good in the tourney as a 6 seed. Beating Siena and Northern Iowa who had upset #2 Missouri and Doug Smith in the opening round. The Gophers came into the Syracuse game a decided underdog. I think they were 8 point dogs. Syracuse had Derrick Coleman and a nice SF named Billy ???? Forget his last name. They were solid but over-rated. The Gophers jumped out to a 5 point lead and held it the whole game. Coleman got a huge Tech for an elbow on Shikanjanski. The GA Tech game is remembered for Kevin Lynch's desperation 3 that came up short, but I remember another charge/block call going against the Gophers in that game late in the first half when the Gophers had a 8 or 9 point lead. We actually led 40-30 or so with about 2 minutes to go in the 1st half. That charge/block call really screwed us and helped them to close the gap to about 5 by HT. Then they came out in the 2nd half with Kenny Anderson and Denis Scott nailing threes. They eventually built up a 8 point lead before Burton hit 2 long 3's in the final minute to get us within 2. Anderson missed the front end of the 1 and 1 with 5 seconds left. We were out of timeouts and Lynch was fed the ball near half court with 4 seconds left...he took 2 dribbles and launched a running and rushed three which came up way short. Coffey put the rebound in about half a second late. Lynch actually had time to pass to Coffey for a dunk or layup if he had looked up. That was a heartbreaker because we had our chances and let them sneak back into the game late in the first half. They took momentum into the 2nd half and got hot. We should have been leading by 10 or 12 before the half. We also missed the dreaded front end of the 1 and 1's late in the first half to help them come back.
4)1993 - We beat G-town in the final of the NIT. Had a nice season in the Big 10 and finished 10-8 I believe. Most were surprised we got snubbed. I don't remember what our RPI was, but we got robbed. Really nice team with Randy Carter, Voshon Leonard, Ernest Nzigamazabo and who else?
5)1998 - We won the NIT again although it was later "vacated" - I really liked that team. Miles Tarver, Sam, Eric Harris, Quincy Lewis and the JUCO transfer Alexander. Got off to a slow start that season because Courtney James and Charles Thomas were both kicked off the team. Then Eric Harris and Alexander got hot in the post season and Sam and Quincy were steady throughout. We had to beat #1 MSU in the 1st Big Ten Tourney just to become NIT eligible and Eric Harris came up huge hitting about 5 threes. I actually attended 2 NIT games against UAB and Marquette and we rolled into NYC playing really well. I remember beating Tark the Shark in OT to get to the final. I think we beat PSU in the final and it wasn't very close. Alexander was the MVP of the Final Four.
Other great seasons better than the current season: 1980 NIT Finalists. 1989 Sweet 16 team.
This season has a chance to surpass them all....but so far, I wouldn't rank this anywhere near the top 5.
