Rjj was some super boxer.
He had no great defense, no idea if he had a chin or not, he was so fast and confident i can happily say he was the best fighter ever prime for prime.
The reflexes was just unreal and all the showboating was better than anyone else.
I mean, we all would love to imagine putting our hands behind our back and hitting someone but actually knocking someone down thats just unheard off!
