I've been saying Sparty is overrated all year, and while them getting healthier and coming off a bye may make them the most dangerous they've been all year, this is still a team whose performances don't coincide with their record or public image. If they lose this game, maybe they become known as the team that failed late season. They do still have OSU and an improving PSU. They're not in the playoffs, yet. Lots could change about how we ultimately perceive this 2015 MSU team.
However, I do agree it will be an important game, at least to the immediacy of the Mike Riley tenure.
