The WHA hoped to capitalize on the lack of hockey teams in a number of major cities, and it also hoped to attract the best players by paying more than NHL owners would. The WHA successfully challenged the reserve clause, which bound players to their NHL teams even without a valid contract, allowing players in both leagues greater freedom of movement. Sixty-seven players jumped from the NHL to the WHA in the first year, led by star forward Bobby Hull, whose ten-year, $2.75 million contract was a record at the time. The WHA signed European players, previously thought to be unsuited to the North American style of play.
