Tim Swartz is one of the pair of Canadian professors mentioned in this article. The article has also been shown on ESPN.com. Tim and his co-author have shown that pulling the goalie earlier in the game leads to additional point and a half over 82 games, on average, compared to traditional strategies. The article includes this praise for Tim and his colleagues:
"....to the glee of NHL analytics types, pulling a goalie with several minutes to go when behind by a goal has become standard practice for some teams. It took decades of work, but the statheads have finally bent the league to their will."
We are proud to have this particular stathead in our department.
