re: Why eliminating FCS games is easier said than done.

Simple...there is NO FAIR WAY to come up with a conf. game schedule rotation for the SEC if you have some keep it while others don't. & no, they WILL NOT be played as "non- conf." just to keep the rivalries going.
& as far as parity scheduling based on previous year's results, you're creating the chance of teams NOT playing each other as often as they do mow.
