That's the humility of a hockey player, I tell you.
Indeed. I'm reminded of a story told by Kevin Lowe, then of the Oilers, after the Islanders beat them for the Stanley Cup in 1983.
(paraphrasing, since I don't recall the exact quote)
"I went to their locker room afterwards to congratulate them on their win, expecting to see them whooping it up and wildly celebrating ... instead it was rather quiet and subdued, the Islander players sitting there with ice packs on their bumps and bruises, groaning from exhaustion .... it was then that I realized what it takes to win the Stanley Cup"

I'm inclined to agree. What Heiden did will never be duplicated.
