He has an unorthodox style - hands low are considered problematic, but such a style has its pros if you can get away with that (and that is a million dollar question). If some of you guys actually fight a bit, you know that hands low give you better view, better defence against attacks on the mid-low section of the body (i.e. takedowns - which is quite important for someone like Prochazka) and if you have the experience and speed to back it up, you have some time to react even if you get tagged (so you get punched, but you compensate the punch partially with a head movement - it is not ideal, but it is a great help). Some parts of the first round from Prochazka were sloppier and it seems he knows that. I would attribute it to him being a bit undisciplined, nervous and single-minded. He will get better with experience and some mental adjustements. Considering movement - here I disagree with the opinion that it is sloppy. His style is based on reading the opponent, changing stances and angles etc. (he is not exactly Roy Jones Jr., but that kind of approach is a key to understand Prochazka's mindset and style). Obviously the comments like "he would get destroyed by XY" are just rubbish - Anderson and Reyes for example are very different fighters and a reactive counter-puncher such as Prochazka would fight very different fight against them. Obviously he might lose, but such general comments are just random guessing with no value.
