I don't know him personally, but I think that if he's humble, he will reveal his secret to you. Every best player shares his knowledge to let everybody get better on the progress.
The opinion of the others are a bit irrelevant at a point. They might have lost to him and say whatever, but do they know his secret of being the best NRS player? If they knew his secret, they would know how to beat him in the past years.
IMO, there are a ton of people training to be the best in every sport, but only a selected few who know the rules and the tricks of every sport can be the best. It's a matter of practice, knowledge and reaction.
