No he wouldn't. Roy's style of fighting is more entertaining than Floyd's, period. Doesn't mean he's a better fighter (with both at their best, he may have been, I can see the argument either way), just that he's more entertaining.
That is subjective. Your saying that is if it's a fact.
The thing about Floyd is people refuse to give him his props on how entertaining he is the watch. They'll say he's a draw because of his team, he's draw because people want to see him lose, etc. You don't become at draw at his level if you aren't aesthetically pleasing to watch at the end of the day.
In my opinion, he's the most entertaining pure boxer of all time. His fights probably don't have any replay value to the casual fan, but they enjoy it in the moment.
Only fight of his that just so awful to watch was the Baldomir fight. Dude still sold over 800k with Guerrero in a fight that was very easy to predict. People like to watch him fight.
It's unfortunate this turned into a Roy Jones Vs. Mayweather thread.
As for Roy Jones, he was a star in his own right. It does kind of feel he was only a star in the boxing community despite being in movies like the matrix, tv shows, etc. To keep it simple he didn't have the "it" factor these other guys have.
