Roger has a long history of putting hands on women too so I don't think that's it.
Obviously some shit was building up with floyd and his pops, but still, I look at Floyd Sr. as an old man who's just trying to stay relevant. He comes by the gym every now and then and wants to give his son some advice, and of course he'll say he's such a great trainer and all that, again, just trying to make himself feel relevant, useful and important. Floyd, after that I thought was pretty damn cold hearted, saying he aint shit as a trainer, putting him down and what not. Looked like senior had tears in his eyes throughout that. In front of the cameras and shit too and calling him a faggot smh.
Felt kinda bad for the old man. Floyd needs to grow up. If his dad is old and crazy, just ignore the "I'm the greatest trainer ever" nonsense, pay no mind to it. Not like anyone in the world actually believes it anyway.
