College football's conference championship weekend was loaded with drama, but in the end it looks like there will only be one new team in the Top Four when the 2015 College Football Playoff semifinalists are revealed.
Clemson held off a hard-charging North Carolina team to lock up its spot atop the final CFP rankings, Alabama dispatched Florida in the SEC title game to lock up a top-two seed and idle Oklahoma had a stress-free day watching from its perch in Norman.
However, the bottom of the picture likely received a shakeup thanks to Michigan State's 16-13 Big Ten Championship Game triumph over previously undefeated Iowa.
