Is MSU at #24 even after losing to Wisconsin?
Yes, MSU current RPI #24 with SoS #42 and B1G 6-6 and NCAA 17-7.
Compare to MN RPI #103 with SoS #143 and B1G 7-7 and NCAA 18-7.
If we beat them at home, we go a full game ahead of them in B1G. For now, our records are quite similar.
Interestingly, MSU played four bottom-100 teams (to our six). Given similar records, one might expect their SoS to be rather high, but not as high as our #143. But what they did in order to get an SoS of #42 was to play two top-10 teams (to our one), plus another 76-ranked team and a 100-ranked team. Their (and our) top-100 NC opponents were:
MSU Opp (Rank) MN Opp (Rank)
Oregon (4) Syracuse (10)
N.C. State (8)
Wright State (76)
Virginia (100)
By the way, the Spartans lost to N.C. State, but beat Oregon and the others. Being on neutral ground, the loss to N.C. State was most likely net-beneficial to its RPI.
So my guess is that the way it sorta works is, each top-ten opponent “atones” for about a pair of bottom-100 opponents. That leaves four “unatoned” bottom-100 opponents for MN, whereas MSU’s bottom-100 sins were completely atoned-for. Plus MSU gets credit-in-heaven for Wright State and Virginia.
In general, MSU has somewhat balanced opponents, but MN has unbalanced opponents, tilted more toward the cupcake end.
The result is something like this. MSU and MN both have natural nRPI near (guessing) 19. Its SoS of #42 is not too bad, but does drag down its RPI to #24. MN on the other hand has a horrible SoS of #143 drag its nRPI of 19 all the way down to an RPI of #103.
You see how RPI is a weighted average of nRPI and SoS, but with a heavier weight on SoS. The nRPI here is just a term I made up to represent the won-loss term in the RPI equation, which happens to be about the same for MSU and MN - to order of magnitude.
The point of the last exercise is to show vividly (without trotting out the similar but complicated true RPI equation) how RPI is mostly a measure of Strength of Schedule, and only to a lesser extent a measure of how good is the actual basketball team.
Therefore, whenever a team (like Minnesota, for example) gives itself a horribly cupcake NC schedule (without compensating via enough top-ten NC opponents), then it is effectively sending an engraved letter to the selection committee, saying “Please don’t invite us to the Big Dance - we don’t want to go - unless, that is, we win virtually all our games - in which case you will notice that and invite us anyway.”
So for MSU and Minnesota, who are virtually equally capable teams, MSU has a nearly guaranteed invitation to the Big Dance (4th among those “in”), whereas Minnesota is first team out (about #8) for the Big Ten.
By the way, Gamer predicts we beat MSU at home, and has that baked into its projection of a final MSU RPI of #23. So we probably won’t knock MSU out of top 25 when we beat them (I’m being optimistic here, but I think it’s appropriate).
By the way, since Gamer also has our projected defeat of MSU baked into Minnesota projection of end of season RPI #91 and SoS of #107, the only way we can improve on those numbers is to also beat the two teams it thinks we lose to, namely Rutgers and Maryland.
So it’s “win out the remaining Big Ten season” or/and “win the Big Ten Tourney.” No pressure!
