Goaltending coaches have long been responsible for providing a scouting report on opposing goalies, and they can become increasingly important in the Stanley Cup Playoffs, when any identifiable weaknesses can be targeted repeatedly over a best-of-7 series. St. Louis forwards praised Alexander for the depth, detail and effectiveness of his presentations on how and where to score on opposing goalies, but Allen's demonstrations added a new twist.
It's hard to find examples of it being done before. One goaltending coach remembered asking his backup to stay close to the goal line in practice to mimic an opposing goalie who played deep in the crease, and another asked his backup to stack the pads in practice heading into a playoff series against Dominik Hasek. During the 2010 Vancouver Olympics, United States goalie Tim Thomas was spotted imitating Martin Brodeur's unique style in practice before a game against Canada, but for the most part, scouting reports on opposing goalies are limited to video breakdowns.
Having Allen channel Rask for the videos appears unique, letting the Blues control the framing of an easily relatable visual addition to the usual trends and statistics for St. Louis shooters.
"Never seen anything like it," center Brayden Schenn said. "I've been in playoff series before, and you see where the tendencies are to score, but they've never broke it down quite in depth like that before. It just kind of gives you a different way of looking at it because Tuukka plays a little different than what most shooters are used to seeing. Obviously, he's still a great goalie, and you have to try and find ways to break a guy down like that. It's credit to David Alexander and Jake working together and doing what it takes to try and win the Stanley Cup."
Allen said the idea was born out of conversations about differences in the first three goalies the Blues faced in the playoffs: Connor Hellebuyck of the Winnipeg Jets, Martin Jones of the San Jose Sharks and Ben Bishop of the Dallas Stars. They had plenty of experience against each of them in the Western Conference, but less so Rask, whose style has some unique quirks.
