MSU has to have the most weirdly fickle fan base. It's not the largest, but when they feel like it, they show up, and then easily stop caring. It honestly sounds like there are more MSU fans there than Purdue fans, just like at Northwestern and Miami (low bar). And I remember when Dantonio first got there, it was similar. IIRC they set the Champs Sports Bowl attendance record in his first year (even playing against Boston College's non existent fan base) simply based off how many MSU fans travelled. Yet like one year removed from the CFP, home MSU games were empty except against like UM or OSU. They are either 110% or 10%, no in between
