those teams have to have places to go. Why would the sec want to double up in markets it already controls with clemson and florida state? North Carolina is probably a safe bet for the bigten but will they go without a brother named duke? Miami just isnt there athletically right now to be a serious candidate for either
Just looking at the ACC...
Clemson has a strong FB brand and a decent enough TV market. I think both the SEC and B1G would have interest.
FSU has a strong FB brand but they don't add a direct market. How much weight does FSU carry in Miami, Orlando, and Tampa? Also one could argue that recruiting in Florida would become harder for SEC teams. I do think the B1G should have interest.
Miami has a good brand and a good market. They are in no way a fit institutionally for the SEC. However they are less of a threat for recruits vs FSU. The B1G IMO should absolutely have interest.
UNC has a great BBall brand and adds markets. Both the SEC and B1G would want them.
GA Tech has a good market. The B1G should want them. The SEC shouldn't offer, unless they want to keep the B1G out of GA.
VA Tech has a decent FB brand. I think both the B1G and SEC should have interest. For the SEC IMO they are the #1 pick for VA, while #2 for the B1G.
UVA wouldn't really fit in the SEC. The only way I see them there is if UNC goes to the SEC on the condition UVA comes too. The B1G fits for sure.
NC State would add markets to the SEC, if UNC went to the B1G. Also the SEC needs to water down a little or fans from the premier programs will have to get used to 8-4 type seasons. Someone has to lose games.
Duke has a strong BBall brand but it is not enough to get an invite. The only thing IMO that can save them is if UNC requires a Duke invite to leave the ACC. Not likely though.
BC adds a good market but they stink at sports and have no fans. Would the TV networks want them? If yes, then the B1G may come calling.
SU has a good brand and a large passionate BBall fanbase. There is influence in NYC and a lot of influence in the rest of the state. Is that enough to get an invite? I think SU and BC will either both go or both not go to the B1G. IMO it is 50-50 to happen.
Pitt would fit in the B1G but they do not add value. I suppose if the SEC needed one more team to get to an even amount of teams, they could consider Pitt but highly unlikely.
Louisville has pretty good athletics, but doesn't add enough value.
Wake does not add value.
I think the top half of that list will either be in the B1G or SEC one day. The bottom half teams could end up in those conferences, but it isn't likely.
