Is he a GOAT or is he a DUCK?
Is he a calculated assassin or an inhibited scaredy cat?
Is he smart or is he an opportunist?
In 20 years time, will people look at him as someone who has done it all, or someone who should have done more?
Does he inspire or does he aggravate?
Anybody who won't get into the cage with a UFC level fighter calling anybody who does get into the cage a 'scaredy cat' is incredibly pathetic. Its like an overweight guy who gets winded walking around the block calling anyone who makes it to the Olympics 'unathletic'.
Having said that, he's neither one extreme or the other. He's neither an assassin (he hasn't killed anyone) nor a scaredy cat (he gets into the cage with UFC fighters).
He seems fairly smart (I'm told his French is educated, and he speaks a second language, which takes a reasonable amount of intelligence), and he took an opportunity in fighting Bisping.
There's no such thing as an athlete who everyone thinks has done it all. Jordan, Gretzky, Ruth, Bolt, Pele, Ali all have their critics. For that matter, so do Einstein, Darwin, Mozart, Michelangelo, Shakespeare; thinking there's someone who everyone is going to say 'did it all' is naive.
And he clearly inspires some people and aggravates others.
