I don't know if it is a lack od admiration (some of those snobs will be there, of course) or rather a case of "not really following what drummers outside the jazz-genre do". My impression is rather the latter, that most jazzers are too concerned with what other jazzers do (which is a full-time-job in itself, as jazz is such a broad musical field) so that they just don't manage keep track with what musicians in other genres do.
I am guilty of that, too. I do realize what the one or the other drummers does, but I would not state that I know who the best/most popular/most sought after drummers in metal, fusion-rock, pop, punk, rock or reggae are right now and what makes them stand out from the crowd. Heck, I even have problems keeping track with what jazz drummers do.
I am pretty much a jazzcat myself but really appreciate what drummers like Paice, Moon, Starr, Blaine, Jackson, Baker, Ulrich, Portnoy, Cavalera, Aronoff, Sucherman, Smith, Botts, Soan, Brazil, Copeland, Bonham, Collins and many more have done. Without them, our global culture would be less entertaining and inspiring. JMHO
