bad for business if 1 fighter holds 2 belts, that mean only 1 title fight per weight class a year maybe 2 for 1 weight class, guys will just wait 1 yr for their shot
realistically after grant and mendes (who both earned #1 contendership) who's shown they should get a shot at Aldo/Showtime?
Lightweight division is a mess. Melendez is fighting Diego Sanchez next?

He should get Benson after that IMO. Maynard just got knocked out, Thomson needs top 5 comp, Dos Anjos is coming off a good win vs cowboy but he needs to finish somebody.
Featherweight divison is kinda a mess too. Between Lamas, Frankie, and Cub one of those three deserves a shot. Lamas beat Cub two years ago, Cubs on a 4 fight win streak since. I'd pair them up, have Frankie go the Uriah Faber route and beat some lower top 10 featherweight/hyped newcomer to the divison. Than Frankie vs Cub/Lamas.
My long and exasperated point is there's time for Aldo and Showtime to fight, and for the UFC to set up legit #1 contenders in both divisions.
