Has Floyd Mayweather Jr poor Sportsmanship?

Question
I watched the fight of Floyd Mayweather Jr and Victor Ortiz.

I can say that the fight is well controlled by Floyd who has a higher  percentage of accuracy compared to his opponent.

However, I really hate to see that he knocked his opponent even if it is still waiting something from the referee.

Does what Floyd showed a sign of an athlete with poor sportsmanship?

Answer
I also watched the fight last Sunday here in the Philippines. But I choose to watch it via Satellite than via pay-per-view. I am not really the fan of these two fighters.

Now, regarding on how Floyd Mayweather Jr knocked out Victor Ortiz... Well, there is nothing wrong with it. Officially, the time for the fight was called by the referee  in which means that the fight will start again as to finish the round.

The only problem is that the referee failed to properly start the fight just like what most of the referee have done  when signaling the two fighters to continue the halted fight for a particular round.

Even if the referee has shortcoming, Victor Ortiz has forgotten the very rule in boxing while inside the ring, that is to protect self always.

But in terms of sportsmanship.... Well, Floyd Mayweather Jr seems short of it. He couldn't just wait for his opponent to raise his globes before throwing the powerful punches. And as proof that he is not really disciplined well by his parents is the way he talk to an old reporter.

If we will look Floyd Mayweather Jr against Manny Pacquiao, you'll realize that Manny Pacquiao even if he failed to take formal education for Secondary school before he went into boxing, but then Pacquiao is more professional than Floyd Mayweather Jr. Pacquiao is more respectful than Mayweather. Pacman is best to be used as model for the kids, while Floyd should not be promoted to kids for it will only bring harm to the kids.
