I'll counter.
The example of RJJ vs Brannon occurred when?
Youth, prime?
That was and is my argument. That fight Roy was in his youth years
Fundamentals don't get lost as one grows older, speed does reflexes do.
So where was that for eight plus rounds against Glencoffe? Tarver?
And that example u listed is about it.
Roy vs Toney P4P fight, you would argue that was NOT Roy displaying talent, youth? , Rather fundamentals? What round?
What actions? DEFENSIVELY or offensively, please elaborate.

And for the statement of assumption, for me it is a proclamation. I even gave examples of fights where he did throw punches -plural. Saying Floyd could have thrown combos but chose not to ...
Is as far to the outer limits of claim Cassius Clay (could) have been a body puncher BUT..
He chose not too.
End game for me: Floyd did put shots together vs Corley, Gatti Augustus & -probably a few rookie fights. He doesn't throw them today because he doesn't throw them well.
Its on you gents: Good dialogue both ways!
