I feel the same way. SU and BGSU are two different animals. One has to play Clemson, FSU, UL, and BC (who would have been WAY better sans an abnormally high number of injuries) every year. The other doesn't. Players and coaching styles that work in the MAC won't work as well on the ACC. The staff will either need to recruit Florida a lot better, or recruit a wider area effectively.
That said, I'm willing to give Dino and the BGSU coaches the benefit of the doubt on offense. His Art's system works really well at Baylor and family atmospheres work well for recruiting. Admittedly, I am FAR less confident in our future offense than most posters (we will have trouble getting Baylor-level talent because we aren't located in Texas and the big players in our hot recruiting areas aren't down). However, I'm still content to give it a whirl. Dino coached at Pitt, so he presumably understands the limitations of recruiting in the northeast.
I'm not completely sold on defense, and I would really like to see an aggressive and attacking defense, like the one that we had under DCSS. A fun defense and a fun offense is, at the minimum, fun to watch. At the maximum, a good recruiting tool that also grabs exposure and creates upsets. However, if Dino is willing to cut ties w/ defensive coaches if they don't pan out, and if the school is willing to pay for top-level talent to replace them if need be, then I'm willing to give our MAC D coaches a spin for a year without too much complaining. Who knows, they might actually end up being really good, and that would be great.
And before anyone blasts me for being skeptical of the MAC. Yes, I freely admit that a lot of great coaches started in the MAC. However, (even more) terrible ones started there, too. The average MAC coach is worse than his counterpart at most other conferences.
