Looking at Emmett and Burgos and then considering the small cage is in play makes for a tough choice. I think at this point the cage, the short notice and the unusual training situations(for some fighters) do have to be considered in capping.
Josh Emmett has big power, thick through the trunk he's able to generate a lot of torque and gets his body weight into every punch. A down side of this is he doesn't show a lot variety, he wants to land that power always. He leaps into the range with big hooks, right/left or sometimes two right hand hooks and the left but it's all power shots and in a quick burst and then back out. He's always looking to land the big hook or the big over hand, he has some kicks to the leg, he has a jab, but they aren't a big feature of his game. His game is all power, head removing swinging from the hip bombs.
Burgos is the better technical striker for sure but for such a tall and long fighter he really under uses his range tools, the jab is there, the low kick is there and a nice front kick up the middle, but he strongly favours boxing range and pocket exchanges. In this space he is very good, nice tight short shots.
A big concern is the danger of playing in that range with a power hitter like Emmett. Burgos eats a lot of shots and has been rocked and dropped and finished in previous fights. Trading shot for shot with Emmett is risky, one bad slip, or a guard just too slow too come back to the chin and you will find yourself knocked out. Both men have big defensive holes, both can and are often hit, Burgos in particular, especially early in the fight.
There is, in a way I think, opportunity for the pressure and crowding of Burgos to help though. If you take the space away from Emmett he can't do that standard team alpha male 'run in over hand' they all use, if Burgos is on him like glue and gives no space it limits Emmetts' options even further.
Burgos lacks true stopping power, Emmett lacks depth, both men lack defensively.
I think Emmett is the more simple puzzle to solve, he doesn't have a deep bag of tricks to draw from, but small mistakes can cost you massively.
I can of course see Emmett landing the bomb and ending the show, and that will be a threat through out the whole fight, but over all I think Burgos can land the cleaner sharper punches, pressure Emmett to back up to the cage and find a rhythm and pace that Emmett wont be able to match.
The ITD and under 2.5 are likely to hit here, the small cage will make for a pressure cooker and one man will likely crack, I will look to play this, line depending.
I bet Burgos pre-tape for 2 units, post tape I believe I will reduce to one. I do favour Burgos to win the fight, after probably a rough first round (If he survives), and I feel he has more ways to win, a decision or KO/TKO is on the cards, where as I think Emmett is more likely KO or bust.
