chance it stops, or at least slows down.

ESPN is paying the B12 and the ACC, but they get more bang for their buck with the SEC. It is obvious that they will promote the SEC like crazy. The B10 is competing against ESPN, so it makes sense for them to pay to weaken ESPN properties. The easiest targets are the ACC and B12. The SEC's success in the last 12 years of 'playoffs' makes it impossible to say they are a better product.
