Gordon (20-7-1) is a good striker although without KO power. He lands and stays active, so he will win if it remains standing for the duration. Moises (19-8) hasn't shown a great takedown game at on 35%, but he has good low/body kicks, is decent enough on the feet...if he just finds one takedown it may be enough. He's underrated in the division after fitting several top guys. he has power for a KO with both kicks and strikes plus he'll be a sub threat on the ground. I like "Flashe's" story but his skill level is just borderline UFC IMHO.
Costa (23-7) is much fresher with better cardio. I could see Erosa (33-11) an early threat but I think he will get finished in the 2nd half of the fight...likely by submission.
Santos (15-1) has shown improvement each time since winning the Ultimate Fighter. He is 2-0 and although he did not look great in last fight, a split decision win, he still has the way higher ceiling. Yusuff (13-4) has more experience in the octagon but hasn't fought in over a year since losing 2 straight. The Brazilian is 7 years younger and will be much hungrier tonight.
Morales (17-0) has looked awesome so far going 5-0 in the UFC with 3 finishes including a R1 KO of Neil Magny just 8 months ago. He's a physical specimen and will have a 7" reach advantage. He loves to strike, has an excellent jab with powerful kicks along with amazing TDD over 90%. But Burns (22-8) still has a lot left in the tank. Even though he's lost 5 fights in the last 3 years, they were all to ELITE competition: Brady, JDM, Belal, Khamzat & Usman. I do lean towards Morales getting the win, but this falls into value bet, how can the #6 WW with his resume be a +500 dog? Well even at +400 since it has dropped a bit, I'll get some.
