He'll fight once more, but there is no need to rush that fight either, that fight will then let us know where his head is within the sport. If it goes the same way there will be no place for him, your points are all correct and his mind took a beating as well this time.
That is a great point that I forgot to mention.
His body language was awful. Especially at the point of the stoppage. He didn't want to continue.
At times you could see the confusion and hesitation on his face when he realised this guy wasn't standing there to be hit and was firing back.
