Add to this a step up in quality of opposition.

Wilfredo Rivera was undefeated untill he met Whitaker x2, DLH, Mosley, Vargas and after five nearly straight losses your just not that much into it any more.

Fernando Vargas undefeated untill he met Trinidad, DLH, Mosley x2 all of a sudden he turns into a shot fighter in his twenties. Just too many beatdowns in a row.

It's the same thing with the lesser known fighters. Only that it happends at a lower level. Once a fighter reaches a level where they can get beat, most of them get stuck there. They keep trying to brake through that level and keep fighting at that level of competition, but they are just not good enough to break through and they end up loosing most fights untill they just loose interest and loose that hunger they once had.
