If you want to become great at something, then you’ll have to become laser-focused on it… And if you want to become the best at something – well, then chances are that almost nothing else can take your time other than your craft.

Roger Gracie sees that in John Danaher, whom he has the highest opinion of.
He shared his thoughts in a recent interview with Lex Fridman:

John Danaher is super smart, an eccentric. And he lives through Jiu-Jitsu. I mean, he’s 24/7 thinking of better ways to teach, how to make his competitors better.
And that, as a coach, when you have that dedication as a coach – that makes the most difference in your athletes.

Roger continues by emphasizing that no other coach has the level of dedication that Danaher does:

And which [other] team do you have with a coach with that amount of dedication? All the other schools, it [the coach] is someone who competes [at the same time as coaching].

For example, Andre Galvao. He’s a competitor and he brings up the hype in everyone else; but he doesn’t have the time, he doesn’t spend time working individually… I mean, I am sure he does, but his time is limited because he is also a competitor.

In other words, John Danaher is completely dedicated to his athletes:

Nowadays, all the leaders – all the main coaches for the other big schools – they have other things in their lives. They’re not fully dedicated to their athletes. And John is.
