Was Mike Tyson trully great or just lucky he was chosen by Cus D'Amato as his last fighter to train?

Anyone who is familiar with sports understands that even in individual sports the team around a contender makes him/her rather than visa versa. Mike started out a highly disadvantaged child in a dangerous and poverty stricken part of America. Even before he reached 13 years he was already well known to law enforcement and was set for a tragic life of crime. As the story goes it was then that he lucked into meeting the legendary trainer Cus D'Amato. Other boxers would have given their high teeth to be trained by such an awesome man and Mike was lucky enough to be the last he would train. Inevitably he would p on everything he had learned in his long and illustrious career in boxing and hand Mike an incredible legacy in terms of the team he left to look after the young contender in the form of Kevin Rooney, Bill Clayton and Jim Jacobs. The subsequent glory and fall from grace is well doented. Why did Mike choose to turn away from a team handpicked by a man who even adopted him to give him a sense of family?. He certainly had a champions spirit and a fighters physique and it seems good heart but the torch of greatness only burned briefly left in his own hands. I believe Mike Tyson is a case in point that the team around an individual is all important. The success that an individual achieves often outshines the team blinding even the champion to his own limitations and the subsequent inevitable failure.to come.
