Cagesideseats website had a pretty interesting article regarding the WWE's Women's division and the Divas/Women's belt being sort of a curse for one's career.
Winning the belt basically puts your career at a 50% chance of lasting a year after the reign ends in the WWE. 30% chance of lasting after 2 years.
Only Natty and Alicia Fox have managed to have decent careers without needing the belt in the WWE since their last reigns were 6 years ago.
