All top class NH players, not all remotely world class however I'm not going to argue the toss on individuals for that way lies conflict & I do try hard to be nice, the tea-leaves told me that would be best.
Suffice to say that world class labels means very different things to different people & I don't share your, in my view, rather undemanding definition.
I'd go along with what you say. Players need to be a bit special like Woody, BOD & POC - the only 3 in the professional era that I'd put into that category.
England had a load for their world cup win - D'Allalio, Johnson, Wilko, Hill & Robinson for starters. They just peaked for the '03 world cup.
Of the present contingent I'd say that Healy is probably the only one who would fit into that category (and he isn't there just yet).
Edit: A fit Ferris would make it as well, but he is never fit for long enough and proably mostly plays carrying an injury.
