I know you're asking this as a joke, but if I'm being honest... JoMo's problem wasn't his offensive scheme. I think his offense could have eventually worked, but I think it's harder to get the personnel you need to run that offense at Mississippi State and we sure as hell didn't have that personnel when he got here, so it was a square peg/round hole combo.
I think it's easier to get the personnel you need for Leach's offense because it's much simpler.
So, I guess it depends on how you define 'better'.
