Defend within a year or you lose the belt. Other sports that have annual world championships don't care if the last champion is there (maybe from a financial perspective). Injured? Too bad. Schedule your first defense in 4 months to give yourself time if an injury occurs. There's a reason few sports have repeat champions at annual events. Those that can defend such annual titles are truly great.
I have no delusions that MMA is far harder on one's body and riskier to one's health than say tennis or shot put, so number of title defenses is more important to me than number of years as champ.
