A book called The Hockey Compendium by Jeff Z. Klein and Karl-Eric Reif showed that the minimum of Hasek's goaltending performances from 1993-2001 was better than the largest ever goaltending performance going back to WWI. He was the RJ of goaltenders. (Quoting Hockey Stars magazine in 1996, "Jeanneret is, hands down, the best TV play-by-play man in the NHL and he's so far ahead of the rest that there's no second best.")
Having said that, the youngsters have to go see the highlights of OJ's career to understand exactly how good he was and how mediocre the Bills were for most of his career. 5 down linemen, 3 LB, and the SS in the box? No problem.
