Not to be picky, but Ron went on to play for Northampton Town when he left the Wolves. I started watching Wolves in the 59/60 season and listening to my Dad and elder brothers, there was only a fag paper between that Cup winning side, which incidentally should have done the double that year - but crucially lost at home to Spurs in the crunch match (my first game) and the title winning teams of the early and late 50's.
My own opinion as to why we never really pushed on, was the boards refusal (maybe Cullis - not sure) to sign Scottish and Irish footballers. While the likes of Law, St John, Crerand, Best (big Wolves fan as a boy), Blanchflower, Giles and many many others were being hoovered up by what are now the big clubs - Wolves policy was to buy English and with the £100 wages being scrapped (as someone has said) we just weren't prepared to compete in the market.
