The oncoming weekend of college football madness begins this afternoon, when the two Carolinas, North and South, battle each other at 5 p.m. ET on ESPN.

At 8 p.m. ET, also on ESPN, is another game, TCU vs. Minnesota – and the importance and fun of all these meetings, and more, is explained by Gerald Jordan in his Crossing Jordan blog.
