But in Pollock's case it was the technique itself, not the lack of technique. You might be right that people don't really go "wow that Keith Moon trailblazed the Moonie technique" but people who don't particularly care for his technique still admire and recognize his style. I'd say that's probably the best you can do as a drummer, have people listen to a song and say, "wait, is that Grohl drumming?" I've had more than a couple guitarists tell me to play like Keith Moon on a song, and I know exactly what that means. I'll bet Townshend wrote songs for his style. That's a pretty powerful testament to his presence and legacy in pop music.
Townsend also blamed his partial deafness on Moon, which is pretty ignomious.
