I think both of them are the two best in boxing today. It's hard to go with who is better. I lean towards Roger because of his work with Floyd Jr.
Who else have Roger trained apart from Floyd jr.? And btw Floyd jr. leaned almost everything he knows from Floyd Sr. not from Roger. I pick Floyd Sr. and it shouldn't even be a discussion.
I know Roger personally and I've met Floyd Sr. on a few occassions. Both great guys. I just think Roger is better.
