I get it, he is your favourite and will be for some others, but to call him Mr Middlesbrough is definitive and he is not nearly that in my mind, not even close.
Brian Clough scored way more goals in half the matches, whilst playing alongside Peacock who was more prolific than Hickton anyway in terms of goals per game. Both Boro lads too. They are just two who are more significant in my mind.
All of them were in the second division; we have had top flight superstars in different eras too.
We all have favourites, not all the same.
