The ACC Network gets a bump with DFW and the Bay Area I guess, but its not THAT big of a bump. The ACC is paid about the same as the B12, so lets, for simplicity, call it $35m.
If Stanford, Cal, Oregon State or WSU were worth $35m, why isn't ESPN putting them in the B12, since they just paid for that for the 4 corners? Clearly OSU/WSU are not on par and probably value out closer to $15m, which will help the MWC. If Calford IS worth $70m combined but turned down the B12, then you could make it make sense I guess, but only for a short period of time. At your 60-70%, that only amounts to $25m/year back to FSU/Clemson to split, but then they have to ship a fuck ton of other schools out to the west coast? I mean Washington mentioned $10m in increased travel to the B1G, but they'll be making $80+m in six years.
Its all sunken money. They'd be better off saying, "you play in the playoffs you split 50% and the remaining 50% is split to non-participants." That would make Clemson/FSU waaaaay more money in the short and long run as the ACC will likely be making $100-150m a year from the post season going forward.
