I do think he fights much better when he feels he has something to prove. I don't think it's a coincidence that his two best performances were in fights he was the underdog.
He seems to be better in big fights he rises to the occasion and levels up his game when the stakes are high.
The kambosos fight is a complete fluke.
No such thing, only way to prove otherwise is to face Kambosos at 140 in a rematch
