The more likely outcome, should he KO Anderson, is that he'll get a rematch with Lawler for the WW title.
Once upon a time he KO'd Lawler. It'd make for a good chance for the new and improved Lawler to avenge that loss.
Every Nick Diaz fight seems to be a retirement fight
Lawler gets absolutely raped by Diaz even worse. But yes it's real important that fight happens for title or no.
Yes, if and when he loses. This is his big payday. Losing this will make him not relevant anymore and there are no fights to make for him.
nick diaz doesn't strike me as a financially responsible guy so i could see him retiring and re-surfacing a couple times
Yes he will retire Anderson.
