Well..aside from those of us lucky enough[or unlucky] to be old enough to remember from 1967-1970 when we won almost everything,then i am afraid the rest HAS been pretty shite!
We came 4th in 1972 when we should have won the league.In 1974 we lost to Wolves in the league cup final.We won it in 1976.We were runners up in the league in 1977 to Liverpool.Aside from the cup final to Tottenham in 1981,which we lost,then yes,nothing much to shout home about except maybe the thrilling football under Keegan for a season and that was not in the top flight.I suppose we could add the play off final against Gillingham but aside from the importance to where we might be now,it wasn't much to shout about either was it,scraping out of what was the old third division.
