When the National Hockey League went through labor strife, it used the opportunity to reform the sport. Along the way, it added rules changes to open up the game, such as moving the nets out from the boards to create more space behind them, pinching the blue lines together toward center ice for the same reason, and allowing the two-line pass. It also stopped permitting players to freeze the puck along the boards, which has done much to speed up the game, as anyone who remembers all those stoppages and ensuing face-offs can attest. But when the National Basketball Association had the opportunity to make some necessary rules changes while it was rewriting its labor deal, it was all too eager to get back to business as usual—including the utter scrapping of the rule against traveling.
