The thing with Carvahlo is his boxing is pretty poor, against Manhoef most boxing exchanges were 50/50 all of his kos are setup with his kicks, so im not sure if he can actually knockout a guy as experienced as Lyoto with a kick.
Also Carvalho grappling sucks so if Lyoto can catch a kick and take him down he's probably gonna win that round, is gonna be a close decision as always specially with Lyoto being so cautious lately, he's gonna be moving backwards all the time and thats not a good look to the judges, however who are the Bellator judges in hawaii? Are they biased at all?
Carvhalo resume looks pretty poor in hindsight too, wins over Sakara, Schilling, Halsley and Manhoef dont really scream worldclass and in his big step up fight he got smoked, its not like he's training at ATT or anything so we really cant expect him to turn the corner any time soon, he's not gonna be able to pressure Machida with his rudimental boxing so they're just gonna trade kicks all fight and that makes this fight a coinflip. i wanted to bet Raphael at +120 but at -133 im having a hard time pulling the trigger.
Lastly Machida has been fighting very risk averse lately, he knows guys have figured him out so he no longer commits on his predictable counters and just peppers guys with kicks, thats gonna make him hard to knockout, its really a matter of if Carvalho can be smart enough to steal the rounds with his superior athleticism.
