As we close out rivalry week here at SB Nation, we,should pose the tough question of asking as Michigan State Spartans who our true rival is. Be honest with yourself, as much as we hate the Michigan Wolverines, if you had to pick a school in both sports that has been the team we battle it out with for conference titles, wins that matter in post-season bowl game or tournament selection, and have generally just plain mattered more, you are lying to yourself if you don’t pick the Wisconsin Badgers as the first school that comes to mind.
