JDS will need to get his hands going early to have any chance -- and I really don't know if he can do so. Cain is just so much more consistent. Although I want JDS to win I gotta go with the Mexican American by TKO in the 3rd.
Cormier vs. Nelson? This only goes to the ground if Nelson can somehow rock Cormier on his feet. But for the first time in ages, maybe even ever, Nelson will be fighting someone shorter than his 6ft frame so I think he misses badly with his overhand rights. I think Cormier wins by KO mainly due to the fact that all those punches Nelson has absorbed over the years will finally catch up to him.
Melendez vs. Sanchez @ 155: Melendez by unanimous decision
Jordan vs. Gonzaga: flip a coin? Someone by KO though.
Dodson vs. Montague: No idea who Montague is and this will be his UFC debut. Gotta go with Dodson giving him a rude welcome.
Boetsch vs. Dolloway: Boetsch has lost two in a row while I haven't seen Dolloway fight in ages. No idea.
Marquadt vs. Lombard: Intriguing matchup. This one stays on the feet. I think Lombard tags Marquadt in the 3rd and puts him down.
