Striking expert here. I'd like to give a breakdown of the entire fight in all aspects in order to give you guys a better idea of who to bet on. I'm going to divide this into categories. Punch strike/Kick hitting, Ground Battling, and Mental Spirit. Punch Strike/Kick Hitting Arguably the least most important aspect of fighting, the ability to finish the fight while standing with hits that come from the fists and legs will come into play in this contest. Junior Dos Santos is the obvious ahead here. He already completed the fight with Velasquez via punches to the dome which put him to the ground forthwith and without hesitation. It was a quick and well set up overhead right fist destruction that Velasquez never saw coming. But will lightning strike twice? We shall observe. Dos Santos utilizes a mix of western boxing and eastern punch fighting techniques which are both powerful and strong. His ability to end the fight at any moment is imminently true. But can he kick and will that come into factor? Velasquez can kick and punch with awesome vigor as displayed in Bigfoot. He may not be refined to the degree of Dos Santos but at the same time. Ground Battling Velasquez may very well have the edge summarily. His techniques in the ground game are coupled by few. His BJJ is notched at the top, his wrestling is effectiveness, and he wins. Dos Santos has proven to be elusive, avoiding the ground, when necessary. His ability to strike shines in his ability to not be on the ground, when unnecessary. This fist fight will stay standing if Dos Santos dictating or on the ground if Velasquez dictating. The outcome will determine. Mental Spirit Ask yourself right now: "Which of these opponents I can see not be intact mentally in the fight considering the hardships that can endure itself?" The answer is obvious. The ability to take punishment or recover from the damage taken or to prove yourself as one than can have it happen to you even if you lose and later come back to be better can be the biggest aspect of a fight that continues longer than you anticipate given the circumstances you expect to have happen or will happen despite your preparations and readiness for what you expect. I consider this fight to be closer than many give credit though I think these criteria will help you determine the winner.
