I would say CPF's system had much better results (at a higher level) than Clawson's.
Yes and no.
CPF's system didn't seem to do a whole lot without Cutcliffe... which begs the question of whether it was the system or the disciplined, execution oriented approach of Cutcliffe.
BTW, Clawson's system is similar to offenses used successfully in the NFL.
I argued that Fulmer wasn't getting in Clawson's way at the time. In many ways, I think he didn't. In two critical ways I think he did.
One, with 2005 fresh in his mind, he wanted to avoid a QB controversy at all costs. That decision helped no one including Crompton.
Two, it was HIS philosophy, not Clawson's, that says you "throw it all at them and see what sticks". That works with the old system which really wasn't a system but rather a playbook containing every play known to man. Clawson, like CLK btw, has a system that has to be built from the foundation up. He did it everywhere he went. It is very likely that he told CPF that it would take a couple of years to do it his way (since Scott told Briscoe that this was the new coaches' understanding). CPF more than likely rejected that idea resulting in the O being installed in a fragmented way.
I defended Fulmer when I thought he was right.... which to many made me a "fulmerite". But Clawson didn't cause his downfall. The fact that he let Chavis be a lazy recruiter and let Sanders stay around as long as he did and lost his momentum in recruiting... and lost team discipline..... had nothing to do with Clawson or his system.
Clawson is far more a victim of the circumstances cultivated by CPF than CPF is a victim of any flaw in Clawson's system.
