Since we are playing "just for fun", I would like this arrangement for a new conference. I am not naive enough to think this could happen easily, but it is wishful thinking.
I will leave out North Carolin, Duke, Virginia, and Virginia Tech, because all of these schools, in one way or the other, are holding back the expansion of the ACC.
Of course, this would take a few teams stepping out of their present conferences. I really don't think two of these schools are that entrenched in their respective conferences.
I think Penn State was just looking for a convenient conference when they joined the Big Ten. Either the Big Ten needs to add Notre Dame or Penn State needs to switch over to the North Eastern schedule of teams.
South Carolina is not as entrenched in the SEC as most of the other teams. They have been out of it in the past.
North Division
Boston College
Maryland
Syracuse
Penn State
Pittsburgh
West Virginia
South Division
Georgia Tech
Clemson
South Carolina
NCSU
Miami
FSU
I have thought about the possibility of teams from the same State knocking each other out of the championship game. It really is insignificant in the big scheme. If you are good enough to be the champs, you need to beat your in-State rival.
For instance Clemson could lose to a South Carolina, win the rest of their games, still have a great season, and go to a major bowl. So, it really is no big deal.
The same with FSU and Miami.
How about a season with this sample schedule, assuming we play six games within the league.
GT vs Vanderbilt (OOC), Rotate Kentucky
GT vs Miami
GT vs Ole Miss (OOC), Rotate LSU
GT vs Clemson
GT vs Auburn (OOC)
GT vs NCSU
GT vs Tennessee (OOC)
GT vs FSU
GT vs Alabama (OOC), Rotate Florida
GT vs Boston College, Rotate N. Division team
GT vs South Carolina
GT vs UGA (OOC) Make UGA the doormat
This schedule would sell out BDS every year. I may be old, but I still can dream.
