Two reasons:I am actually pretty shocked they did this
1. ESPN is increasing their investment
2. The CFP Committee is placing greater weighting on SOS/SOR and that has hurt bubble SEC teams in the past
I'm just waiting for them to announce a 5+11 CFP format where the SEC knows it's likely going to get 4-5 of the at large spots in a given year for a total of 5-6 playoff teams.
