They'll attempt to do so again tonight (Sat., Oct. 8, 2011) in the main event of UFC 136 at the Toyota Center in Houston, Texas.
The 155-pound championship has been in a suspended state since UFC 125 on Jan. 1 when "The Bully" failed to find "The Answer" to finishing Edgar and went home pissed off and empty handed after cageside judges couldn't make up their collective minds.
Anger can be a crippling emotion but motivation fueled by failure can be equally as powerful.
While Maynard was unable to defeat Edgar in their second meeting to kick the year off (read all about that incredible war here), he does hold the distinction of being the only man to hold a victory over the lightweight king.
That victory, however, came all the way back in 2008. With everything that's occurred in the meantime, that seems like light years ago.
Edgar holds victories over Hermes Franca, Sean Sherk, Matt Veach and B.J. Penn since then. That's an impressive resume and one that should serve to remind fight fans how exactly how dangerous the New Jersey native really is.
Maynard has yet to truly taste defeat, although he might tell you otherwise. The draw on New Year's Day felt like a loss to him, especially considering the fact that he didn't get to go home with the title he's spent his life working for.
He's got one more shot to grab that belt and take it for himself tonight. Failure is not an option. Can he do it?
