Actually the move, eventually, would be more likely that CCG would be play-ins for the playoff... I doubt we see the demise of the CCG any time soon
It could go both ways and both ways are bad.
One is the way it is now, in which the SEC plays itself out of the playoff. With conference champ criteria, it becomes virtually impossible, even for a #1 team going into the SECCG to make it in with a loss. On the other hand, winning the SECCG is not a guarantee the team gets in (although most years it would be). The reason the Big 12 hates the CCG is because they see it as a way to play themselves out of the national championship.
The other option is far, far worse and that is that the winners of these games automatically gets in. This is basically a repeat of the way the BCS bowls are now. You know, Georgia is out, Wisconsin is in.
The SEC had a chance to fight to keep things from being overtly biased against the SEC, but Slive was so happy about a playoff he let them railroad him into having the part about conference champs. The only thing that worked right about the BCS was the rankings and they are basically getting rid of those. So, now it's the BCS brought to you by the people that selected Northern Illinois, Wisconsin, and Louisville.
The SEC has Georgia, Texas A&M, LSU, and South Carolina left out in the cold in favor of those programs. The SEC had better get used to that feeling...
