you're spot on with the rest of your post, but that part is bollocks.
Their dedication and passion for the sport is what made them successful. Especially Vitali who showed what's in him vs. Lennox Lewis.
They were well deserved at the top, just looking at Wlad's body of work.
Also I'm not sure why you say "they" ... Vitali has been retired for years now. Because he's in his brothers corner? Lol.
Don't expect Vitali to return and spank Tyson Fury.
I used to dislike them too for many years, but eventually I had to evaluate between their success and my perspective on them.
