I think Melvin can take him honestly. I don't think Diaz is going to be able to get the fight to the ground. Diaz will have to stand and slug it out and I don't think his slapping punches are gonna work with Melvin. Melvin could take this one by knockout
I've got Diaz by submission on Melvin. And Maynard by UD over Huerta. Apart from those fights I can't remember whose fighting. Oh and I think Condit should win.
Same, also pick Quarry (the other fight on the main card) to win his fight. Nover vs Stout is the best fight on paper in the prelims, Nover badly needs the W.
Huerta Vs Maynard should be the main event IMO both guys are around top 5, diaz is not even close to those two guys yet. Maynard has been unstoppable and Huerta isn't far behind.
Looking at the track record of Diaz and Guillard ,id say Diaz wins by submission. I think Maynard will KO Huerta.
