Why do people still call Floyd Mayweather a "coward" or chicken?

I know the reason it started was because he refused to fight Pacquiao and people were mad about it and ESPN called him a coward in 2010.

They eventually fought in 2015, and even after Mayweather defeated Manny Pacquiao, people still called him a chicken, coward, p*ssy etc.

I think its extremely unfair for Floyd. He has boxed as a professional for over 20 years and has stepped into the ring and risked his health and even life 50 times. Also, fighting in front of large crowds, against boxing champions takes balls.

Yes he is arrogant, and can be easy to hate on due to his persona, but to call him a coward is just stupid

That's just their opinion.
Rightly or wrongly every poster on this sight has an opinion.
Odviously some are that mayweather is a chicken.
Which to me is absolutely crap but it's still their opinion.
