Snyder could absolutely win big at Alabama or the likes. Would the starting rosters look different that if Saban, were there? Yes, absolutely. I think the percentage of the team that would "buy in" would be lessened. But those that did would be collectively better than the higher percentage of athletes that buy in at KSU.
My point being that stars absolutely matter. Would Snyder and/or KSU be able to keep a roster chalked full with them happy? No, but I'll take running off 50% of our 4/5 stars, provided we get a decent amount, and the rest of the team filled with players that Bill typically recruits now over a team full of the way we recruit now.
That said, all I care about is W's. I don't care who is coaching, who is playing, who is in the seats. DPs and W's are all I care about.
