Now, on to the fights.

Main Event – Heavyweight

Yes, Josh Barnett is still competing in the UFC. We haven't seen him since December 2013, but he gets back into the octagon Saturday. Barnett has been around quite a long time. He is 37 years old and has fought the best in the world (Daniel Cormier, Frank Mir, Mark Hunt, Mirko Cro Cop, Dan Severn, Randy Couture, etc.). Barnett is also the current Metamoris, which is a grappling jiu-jitsu promotion in Brazil, heavyweight champion. The point being that even though he hasn't fought in the UFC in nearly two years, Barnett keeps active and rust shouldn't be an issue. Nelson is going backwards. He is 39 years old and while he was never a picture of physical fitness, he has looked even worse lately. "Big Country" is what he is – a guy with monumental knockout power and a terrific chin who is hoping to end the fight with one big shot. Nelson has lost four of his last five, although they have been against good competition (Stipe Miocic, Hunt, Cormier, Alistair Overeem). Because of his power, Nelson has a chance to win any fight that he is in. The problem lately has been that his movements have slowed and he spends far too much time standing in front of his opponents. This is something fighters need to avoid, especially in the heavyweight division. I think Barnett should win this fight, even if he is a little rusty. Nelson's game is just too predictable. Barnett will have to watch out for that one big punch from Nelson, but he has enough experience to not fall into that trap that many other fighters have against Big Country. Nelson could be worth a look for those praying for a quick KO on DraftKings, but that's about it.
THE PICK: Barnett

Co-Main Event – Middleweight

This fight isn't getting talked about much, but it is actually a pretty good one. It's a real contrast in styles. Mousasi is a guy who's game appeals more to hardcore MMA fans as opposed to the casual ones. He is slow, methodical and can almost look bored in the octagon. He is far from flashy, but he does everything well. He has 21 wins by knockout, 10 by submission and only six by decision. The former Strikeforce light heavyweight champion is still fairly young at 30 years old, despite all his experience. Hall is a chronic underachiever. He is one of the most explosive strikers and best athletes in the middleweight division, but he tends to come up short every time he faces better competition. Mousasi certainly qualifies as that. I actually like the idea of the aggressive Hall forcing Mousasi to become more active to win this fight. Mousasi's striking is underrated, but we really see it in bunches because he is so methodical. I think Hall has the ability to take this fight the entire 15 minutes, but it is hard to see him winning.
THE PICK: Mousasi

Flyweight

The UFC's flyweight division is getting deeper seemingly by the day, but the problem is that it still doesn't have anyone who can challenge champion Demetrious Johnson. Horiguchi got his shot in April and was dominated the entire fight before being submitted late in the final round. Horiguchi clearly wasn't ready for the fight and it's hard to find fault with a 24-year-old being dominated by arguably the best pound-for-pound fighter in the world. Horiguchi will have a chance to bounce back in this one, but Camus is no push over. Camus is 1-1 since dropping down to flyweight. He defeated Brad Pickett via split decision and lost a unanimous decision to Henry Cejudo, although his performance in the Cejudo fight was by no means terrible. This has a potential to be an all out war on the feet. The strength for both of these fighters is their striking and both fighters, especially Camus, will enter the octagon confident. This should be a close fight, and when that happens I tend to take the younger guy who doesn't have to travel halfway around the world to get to the arena. That being said, Camus is as tough as they come and his DK salary is entirely reasonable.
THE PICK: Horiguchi

Bantamweight

Roop's biggest (and perhaps only) advantage in this fight is going to be his length. It is difficult to believe that a guy who is 6-1 can make 135 pounds, but Roop has been doing it on a consistent basis for the last 2.5 years. If Roop can land strikes at distance in this fight, he has a chance to win a decision. One would think a veteran like Mizugaki would realize that his main objective should be to get in tight against Roop's body. Mizugaki has lost two in a row after a five-fight winning streak, but those two losses came to Dominick Cruz and Aljamain Sterling, so it is hard to get too worked about the two L's. This fight has decision written all over it. Roop probably has more power because of his size, but Mizugaki is just a better fighter. Takeya is a legitimate top-10 bantamweight while Roop is more roster depth at this point. As long as Mizugaki doesn't allow Roop to unload with shots from distance, he should be fine.
THE PICK: Mizugaki
