A fighter's career is dreadfully short.
The sport of mixed martial arts batters a fighter's body over time, and nearly every professional combats the injuries and the stresses of training throughout his or respective career, resulting in a short-lived bask in the spotlight.
For many fighters, the end is abrupt and unfortunate, the result of a serious injury or a traumatic life experience.
For others, the flame simply dies out and sustaining the glory of past years becomes an impossibility.
Let us examine the latter group.

Note: Ranking is determined by a fighter's recent success (or, in this case, failure) and overall demeanor. Fighters who suffered career-affecting injuries were not considered, nor were fighters with 30 or more career fights.
