Would you lose respect for Mayweather if he fought Connor McGregor?

No, he is retired, 39 and fighting the face of the UFC, did anyone lose respect when Couture shocked out James Toney?

Exactly, Couture has been Ko'd multiple times, he took out an old out of shape James Toney, and he is still regarded as a legend in the UFC.

Floyd's legacy is set, he's fought 24 world champions, has won 12 world titles, and is the only fighter to go through five weight classes undefeated. He has nothing left to prove. If he wants one last money score, I say go for it.

His haters have made it clear they will not support him no matter what he does.
