Prior to the birth of the NHL, there was the NHA. The National Hockey Association was essential the forerunner to the NHL. Jack was a star in the NHA, scoring 146 goals in 168 NHA games. Jack was a powerful, high scoring left winger who held his own with such superstars as Joe Malone and Newsy Lalonde.
Had Jack had more success in the NHL, he would have been considered one of hockey's early greats. However, because he didn't, he has become more or less forgotten about.
Same goes for several NHA stars who peaked too early to have success once the NHL came along. But the NHA was essentially the NHL throughout the 1910s.. Therefore Jack and other NHA stars should be remembered for what they truly were - great hockey players.
