He made more excuses than Wilder after the Peterson fight including something about a man in a hat , claimed Crawford hit him with a low blow and denied he quit, when it was clearly a leg punch and he did quit. After all the excuses he made not to make the Brook fight for a decade, I was just expecting some excuses. But if he's saying the better man won, then fair play.
I did think this too. Surely they would have put him in with bigger guys to see how he gets on, in preparation for Khan. Being around Crawford, I'm sure it would have been some gruelling spars.
