Overtime Rules Changes Could Cut Down the Number of NHL Shootouts. March 18, 2015

Are Teams Better or Worse in Must-Score Shootout Situations? December 22, 2014

*This result should not be especially surprising. A team that faces a must-score situation got there precisely because they were scored fewer goals than their opponent up to that point.

How the Long-Change OT could Cut NHL Shootouts by a Third. March 12, 2014

*We should expect that 34.29 percent of the games that go to a shootout under the current rules would instead be resolved by a game-winning goal in overtime (plus/minus 3.45 percent). In other words, if the NHL GMs adopt the proposal to make regular season overtimes use the long change, the number of shootouts in the 1,230 game season would drop from about 166 (13.5 percent of games) to about 109 (8.87 percent).*
