It's a really good point to be fair.
As someone who was lucky enough to be around in the 80s and saw Sheedy play I really liked him and he was one of my favourite players. However if memory serves me right he only played for their reserves or if I'm wrong he didn't play many 1st team games for the RS. So I don't associate him with them.
Benitez on the other hand was revered ( maybe still is ) by kopites and I always regarded him as the personification of the RS and summed up everything that I hate about them ..... a false sense of entitlement , arrogant and half decent.
