He isn't like Roy that much IMO except the speed and power. He's seems taller for his weight class, but Roy was pretty tall at 154 when he started. Adrien seems more of a true boxer, less dynamic offensively. Not that he isn't as explosive, but Roy had a lot more imagination in terms of his arsenal and the combinations he would come up with, while Adrien works behind his jab and technical defense a little bit more. I haven't seen Adrien show he is at Mayweather or RJJ's level even early their career yet, but he certainly has a done of potential. That fight with Ponce De Leon is really a big dark spot for him IMO.
