Says you and nobody else.
You want use elite?
Use it right.
There is only one team to win three outright titles in the time frame you want to use, that is if you go back one more year to 1994. That's Purdue. Nobody has done it since. Note the word "only".
Up until just a few years ago there was only one team with a winning overall record against all B1G teams. Once again that was Purdue and nobody has ever equaled that feat. See the word "only" was used again.
In the time frame you chose, only one team has had an undefeated home record. Once again, Purdue. Yep, there's rhe word, "only again". MSU came close in '98 but lost to one team, oh look, it was Purdue. I guess we can tag the word "only" to Purdue there as well.
Finally, there is only one team with more B1G championships then any other team. Once again, Purdue. Oops there's that "only" word again.
You want to cherry pick stats and timeframes to fit your argument. Anyone can do that.
If you would have said that the '98 MSU class was elite. I would agree. That team was head and shoulders above everyone else for four years. But since that class graduated, there isn't one thing MSU has done that at least one or two other teams have done. You have one extra final four, but everyone knows that if not for a missed free throw by Louisville with 4 seconds left, then that accomplishment would have never happened.
MSU has been consistently good since izzo took over. But you haven't been much better then other teams during that period and hardly enough to call yourself "the elite" team.
