Demian Maia recently earned another UFC welterweight “W†during UFC 153 opposite Rick Story Oct 13, 2012. Before that July 7’s UFC 148, Maia won via TKO opposite Dong Hyun Kim in the first round, when Kim had a muscle spasm. Demian Maia cordially welcomes a bout against Nick Diaz in the future during his Oct 18 interview Tatame.com
“Dude, I think Nick Diaz and Jon Fitch that opponents would surely have much name this division and I would climb fast. The others, I think they are marked with struggles, but these two guys are certainly very tough and they would have proved much I climb in the division.
I think the two have much jiu-jitsu. Both with Nick as with Fitch. Both are good with that, just that I feel more focused on the Fitch’s wrestling than with his jiu-jitsu, and Nick is a guy more with boxing than jiu-jitsu.â€
Diaz has some options for when he does return. There's Maia, Fitch, Koscheck, Penn II, Rory, and Kampmann. A fight with Kos would be hilarious because of the amount of shit those two would talk leading up to the fight.
