I know what you were saying and I answered you.

Had Syd stayed with the band and not gone crazy, and subsequently not been replaced, I don't think Pink Floyd would have moved much further creatively from where they were at the point he did leave. I don't think Syd had that kind of ability in him. David was and is, a much more proficient player and writer. That's not saying Syd sucked or anything or that the music he did with them was crap.

I also responded to your point about Roger being the expendable one. You're wrong. Period. Roger's lyrical contributions to the band far outweigh any criticisms of his singing or his bass playing.
