Personally, I liked the old 10 team conferences. 12 was already pushing it, but 14 makes it near impossible to schedule other conference schools in the current setups. And you sound like someone who dislikes the word "pod," so I'll call it a division. If the ACC added 2 more schools (say WVU and UConn and completely forget ND), that would create the much dreaded 4 division conference with 4 teams per division. But if the ACC could concede with a 9 game conference schedule, those divisions would allow teams to play one another much more often.
Let's say Div 1=UConn, SU, BC and UL. Div 2=VT, UVa, WVU and Pitt. Div 3=UNC, Duke, Wake and NCSU. Div 4=GT, Clemson, Miami and FSU. Clemson would play GT, Miami and FSU every year. Clemson would also get to play 2 teams per each division every year. This arrangement would allow for Clemson (and every other ACC school) to play other schools every 3rd and 4th year OR every 2nd and 4th year with a gap in between. That means Clemson would only miss seeing a fellow ACC foe no more than a 2 year stretch. Heck, even at an 8 game conference schedule, teams would see one another more often.
And this would also work for the B1G and SEC. But 2 divisions within a 14 team conferences is very cumbersome. I think Slive, Delany and Swofford have gone past the point of no return.
