It doesn't matter who the fighter is, some 'fans' just say this as a reflex.
On here we have the idiot Asdfckwit who, at one time or another, has accused every heavyweight - except for Briggs & Ortiz - of being cowards.
Elsewhere I had another 'fan' tell me that Canelo should have fought GGG straight after the Mayweather loss but didn't because he was ducking him and also moaning that Lomachenko was swerving Rigondeaux.
Is that what being a real fan is about nowadays? Not going to fights or the gym & respecting fighters but just calling them names via the interweb
