How will boxing history remember Floyd Mayweather?

It doesent justify him not taking the fight as there is a risk of his legacy being dropped, but what legacy does he have if he doesent take the fight? He'll be nothing more than a good defensive fighter who never managed to get in there with Pacquiao. Great fighters had great fights and never really had to win, but thats because they all were respectable fighters who when it came down to it, stepped up and took on the opposition. Floyd is not, and will never be thought of as a man who would take on all challenges, so he can never be regarded in that way. Despite Pacquiao's similar tactics, he has been put across as someone who takes on challenges always, which is really lucky for him.

Olu G., as the greatest in ring competitor of all time, Ric Flair , said; to be the best you need to beat the best. I could look like an animal if I just went out and KOed a few infants, but how can I be the best if I've never faught with someone who can lift their hands on their own accord?
