Yeah, the record versus MSU may be tied 2-2, but it doesn't feel that way. There's a lot that goes into it. Bigger wins than losses is one. But the programs are just going in different directions. Just view their total W/L records since 2015. Since 2016, MSU is basically a 7-win team. MSU has also been hurt more in recruiting during this time than any other Big Ten program. And then there's the matter of comparing 2-2 to the MSU win% of RR/Hoke. The rivalry is in transition, and it's not happening slowly.
Of course, that all conspires to make the MSU game the #1 must win on the schedule this year. So while it feels like things are peachy, 4 years also isn't much and just like the new M-UW comparison, there's plenty of time for M-MSU to switch directions.
