I wonder how much of his success has been the new Goggin center. If you look at his first six years, he was mediocre, with one good season (23-14-4). In 2004 they broke ground on the Goggin, and since 2005-2006 they haven't been worse than ten games over .500.
I don't know the reason for the sudden jump in performance. It could be the arena itself, it could be a larger University commitment to hockey of which the new arena was just the most visible symptom, or it could be Rico.
What is impressive about York is that he achieves so much success in an aging arena, on a campus where hockey is 3rd fiddle.
