8 Man Grand Prix
You run two titles for a year and you settle all the title challengers. It doesn't "hurt" the UFC to have Maia/Fitch/MacDonald/Marquardt as an "interim" WW champion. But it does hurt to have all these title eliminators run for two years because of a log-jam at the top.
And by the time thats done, Condit, Kos, Alves, Brown, Pyle etc will just all start a new log jam of there own. A long list of contenders isn't a bad thing its the self righteous opinion that there they should be the one fighting for the title that hurts.
