Actually in the current BCS system (last year thereof) each conference picks up an equal share of BCS bowl payouts, including the Big East/AAC. In terms of access to the playoffs any team ranked in the top four will have an opportunity to play for the championship. Yes, we agree the deck is stacked against the Group of Five schools for a number of reasons including SOS. But in terms of "access" it extends somewhat to the ACC. One of the reasons FSU considered leaving the ACC is because they know that a 1 loss team in the ACC will most likely not make it to the playoffs, whereas a 1-loss SEC, B1G 12, and PAC (and possibly Big 10) champion probably will.
The BCS payout is equal under the current system. Under the new playoff system the payout to the Big 5 is still going to be equal. You said the new system will pay the big 4 more than the ACC. Some conferences make more money from TV rights, non-playoff bowls, NCAA credits, etc. than other conferences. This exists today and will continue after the new system is in place. The majority of BCS money is split evenly between 6 conferences today. Under the new system the majority of BCS money is split evenly between the Big 5 conferences. The only difference in terms of money between the old system and the new system is that the BCS money was split evenly between 6 conferences and the Playoff money will be split evenly between 5 conferences now. The remaining money earned by conferences will not change under the new system. Either way, money is not related to the original question.
The suggestion was made that the P4 would make a playoff including 12 teams. The winners of the P4 would each get a bye and the four runners up would get automatic bids to the first round games. The ACC winner and runner up would both play first round games. Two at large bids would also make the first round games. Under this scenario, the ACC is clearly at a disadvantage. I stated that as long as UNC, FSU, and ND are not in the P4, that no playoff system will use wirtten rules and seedings to penalize the ACC. This comment is not related to your quote that the ACC will struggle to get in the new 4 team playoff. I was answering a question about a future idea for a playoff that includes 12 teams.
