Nazareno Malegarie is much more experienced and is a better striker than Silva. This was expected going into their UFC debuts.
Silva isn't a striker, he's a BJJ guy with a heavy right hand. He's kinda like Josh Koscheck and pre-PED Johny Hendricks in a way. If he didn't have power, he'd have to rely more on his black belt in BJJ and live up to his nickname of Netto BJJ.
Reza Madadi can win this fight, especially if he wrestles in R1 and takes Silva into R2/R3. I wouldn't be surprised if Silva gasses after not being able to lead the dance, and instead is on the defensive trying to defend take downs and/or expending energy trying to get back up.
Reza has several negatives going against him in this fight, but Silva is only 2-0 in the UFC: a split-decision win against a submission fighter who is a mediocre striker, and a quick KO over a grappler we already knew was chinny from his prior fight and went on to get KO`ed again two fights later by a wrestler/grappler.
Interesting fight the more I think about it.
