History of the National Hockey League/1992–present/Rules and innovations

The addition of the trapezoid behind the nets is one of many changes made by the NHL since the lockout.

Hoping to reduce the number of tie games during the regular season, the NHL decided that beginning in the 1999–2000 season, in any game tied after regulation time, both teams would be guaranteed one point, while the team that won in overtime would earn a second point. The theory was that rather than playing conservatively to earn a point for a tie, teams would press for the extra point for the overtime win. In the 2005–06 season the NHL eliminated tie games altogether, as the shootout was introduced to decide all regular season games tied after the five-minute overtime period. The shootout has proven controversial; critics have called it a gimmick, and expressed fierce opposition to any suggestion of using it to decide playoff games, though the league has not pushed for this to happen. It has also been argued that teams are playing it safe, taking no chances in regulation in order to bring the game to overtime, where they are each guaranteed a point. The shootout also has many supporters, among them Dallas head coach Dave Tippett, who stated that many fans enjoy it.

The shootout was one of several rule changes made in 2005 as the league attempted to increase offence following the lockout. The two-line pass rule was eliminated, allowing teams to pass from their defensive zone to anywhere in the neutral zone. Previously, such passes could only be made to their own half of the neutral zone. The rule was intended to encourage long breakout passes and create more breakaways. Teams that commit an icing infraction are no longer allowed to make a line change before a faceoff, and goaltenders are now prohibited from playing the puck in the end-zone corners behind the goal line. They are allowed to play the puck directly behind the net, within the trapezoid marked by diagonal lines from the goal line to the end boards.

One of the most controversial changes was the league's zero-tolerance policy on obstruction penalties. The league hoped that the game could be opened up if it cracked down on "clutching and grabbing". The tighter regulations have met with complaints about the legitimacy of some calls,[54] that players are diving to draw penalties, and that officials are not calling enough penalties.

The changes initially led to a sharp increase in scoring. Teams combined to score 6.1 goals per game in 2005–06, more than a goal per game higher than in the 2003–04 season. This represented the highest single-season increase in offence since 1929–30. However, scoring has rapidly declined since, approaching pre-lockout totals in 2007–08.
