Mangino's teams played hard early in his tenure. When you wanted them to just go belly up, they'd win a few and give the team and fan base hope.
This year's bunch doesn't have that. I think part of it is sparkles party boy ways have caught up with him. Definite lack of preparation, there, that Synder wouldn't tolerate. And he, Sharp and others are playing banged up (but that's no excuse, they're playing unlike our best O- and D-linemen). Also have a sad-sack defensive coordinator. That's a very important position, especially with an offensive minded head coach.
And, finally, they're ku. Losing is what they do.
