When they win out and crush a 3-9 Sparty team, they also effectively lock out OSU of the championship game (IF they beat us and I still think we have a close to 50% chance against them) which significantly hurts their chances of making the playoffs. This is especially true if high ranked conference championship participants win their games.
Sparty suffers, OSU suffers
PSU is not a friend, but MSU and OSU must suffer first
