I don't think anyone would argue that Floyd has better technique, but thats not the question. In his prime RJJ was as close to unbeatable as I have ever seen. He gets a hard time on this board from the younger people who maybe only saw him from 03 on. It's like when I was a kid and watched boxing with my old man. I always loved the younger guys, but he would tell me about all these old fighters and what they were in their primes. I always thought he was full of **** because I only saw them when they were over the hill.
Jones and anyone who thinks otherwise has NO CASE. Jones is better in almost every department in athletic terms and a much better boxer. He's even more proven, and Jones gets knocked because of his record. RJJ is a H2H king from 160-175; Mayweather is nowhere near that anywhere other than 130. No contest.
both great talents but i've got to lean towards floyd because floyd has a chin and can adapt to a plan B when he needs to.
