I don't think Sparty has a chance in this one. I don't think they're as good as their hype. The Central game was an upset but not of the earthshattering variety like when Perles's teams lost two in a row to them; CMU had easily the best quarterback and receiver on the field for one thing.
But if Weis loses this it'll be the most damning loss of his tenure. Dantonio is pure Lloyd in one respect: he doesn't have wrinkles in his offense. He just pounds the ball ahead and expects his team to out execute. Not the schematic advantage sort. If Notre Dame loses on their turf it'll mean one of two things, or both: Weis's so-called recruiting genius is bullshit because he can't put enough talent on the field, or his so-called coaching advantage is bullshit because he can't beat a team that throws rock nineteen out of twenty plays. I think the Domers are going to demolish Sparty, but if they lose, it'll be the final blow that exposes Weis for all-time as a huge crock. Last shred of credibility would be out the window.
