Dave Keon, known as one of the greatest two-way centres in the history of the game, was an amazing athlete who spent 22 seasons in professional hockey. He appeared in an impressive total of 1,725 regular season and playoff games in both the WHA and the NHL, and in all that time he picked up only 151 penalty minutes!
Keon attended the famed St. Michael's College in Toronto prior to turning professional. When he arrived he was a scoring sensation who paid little attention to defense, but that changed by the time he graduated from the Maple Leafs training camp. Keon, under the guidance of Father David Bauer and Bob Goldham, transformed himself into the epitome of a perfect hockey player. He combined skating and stick handling gifts with superior hockey sense in all zones of the rink, both offensively and defensively. He became so good that he was the pre-eminent checking center while remaining a top offensive force.
At 5'9" and 165 pounds Keon was hardly a big man, which often made his task of shutting down the opposition's top scorer that much tougher. But Keon was tough in his own way. He was strong though slight, and mastered the art of angling opponents out of harm's way. While no one questioned Keon's heart or toughness, he always preferred to play within the rules. He won the Lady Byng as the NHL's most gentlemanly player in both 1962 and 1963. In fact he averaged only 6 minutes in penalties in each of his NHL seasons.
