Stallings problem, or, OK, one of his problems, is that while he had no problem throwing Artis and Young and others under the bus he never seemed to hold himself to quite that high a standard. The difference is that when Capel is talking about his guys not playing well enough (for instance) after the West Virginia game he was also couching that in "we've got to do a better job coaching them" and "we've got to do a better job preparing the team" and stuff like that. Even if he doesn't really believe it (and I don't know if he does or not) he isn't just saying the players weren't cutting it, he made a point to say the coaches including himself weren't cutting it as well.
Stallings blamed the players first, last and always. At least Capel says the coaches have to share the blame with the players. That's huge difference, and one that I guarantee the players notice.
