[Lord Didsbury]

Anecdotes about refs don't help. Research does, and research shows that referees have improved so much since the war that "home advantage" due to poor refs now doesn't exist.
Fitter, more correct with decisions etc.

You'll get former players slagging off the standard of refs but that's just selective memory I'm afraid. I think if people really remember how awful refs were in decades past they wouldn't slag off modern refs.
