The point is, he is'nt rubbish, he might not be doing anything overly impressive technically, but it just is not required by the band or the music they make. He doesn't make mistakes or play out of time.
You want to see something impressive that he has done?
Pick any pink Floyd album or song, the songs you like are good because of every element being right.
It's like you are trying to say he was rubbish just because he did'nt play fast aggressive drum solos with fireworks explosions going off, that might be ok for rainbow or motley cure or some hard rock or heavy metal band, but it's Floyd, it's a completely preposterous statement.
He himself would probably admit he was lucky his life went the way it did, and that he is'nt the most impressive drummer, but he is'nt bad or inadequate and his job and is an important part of the pink Floyd sound,
David Gilmour rarely played anything beyond the Pentatonic scale, but has made some of the most amazing music ever, and is one of the most revered guitarists in the world, yet his technical ability is arguably crap.
Mostly, in general, drums are'nt that noticeable, same as bass, you only really notice them when they are gone or played sloppily.
