Are there BJJ heads that don't care about MMA?

Just to preface, outside of maybe 4 or 5 intro classes many years ago, i don't do BJJ at all.

Not really technique related, but i'm curious if there are high level BJJ practitioners you know that pay very little attention to MMA and are focused 100% on BJJ, watching BJJ matches, training BJJ, following the top guys etc.

It seems like every martial art is automatically compared to "MMA standards" in terms of this or that would or wouldn't work in MMA and that is the only thing that matters....
