Rask and the Bruins went 1-5 in potential closeout games that season, losing Game 5 and winning Game 6 against the Buffalo Sabres in the first round and losing four straight in the second round. In those six games, Rask had a 3.50 GAA and an .884 save percentage.
He was 23 years old then, in his first full season in the NHL, having won the starting job from Tim Thomas, who helped the Bruins win the Stanley Cup in 2011 (and who would later win the job back).
Rask, 31, is now a fully formed goaltender in his own right, the Bruins starter for six seasons. And since that devastating 2010 postseason, Rask has done far better with the chance to finish series, going 4-5 combined in the 2013 and 2014 playoffs, helping Boston to Game 6 of the 2013 Stanley Cup Final, where it lost to the Chicago Blackhawks.
In those nine games, Rask had a 2.44 GAA and a .913 save percentage, not as good as his regular-season numbers, but far better than his overall closeout-game statistics.
"He's been our backbone," said defenseman Adam McQuaid, who is in his ninth season with the Bruins and has seen all of Rask's NHL ups and downs. "He's been really solid for us. You especially need that in the playoffs. He gives us the confidence knowing when he's in there that he's able to keep us in games. … No doubt he'll be ready to go [Saturday]."
His teammates aren't worried. They're not looking at the statistics. They're not looking at the past. They know the game will be tough, given that the Maple Leafs will be trying to stay alive, but they believe they're prepared. They believe Rask will be ready, and that'll he'll do what he's done throughout this series to get them through to the next round -- again.
"We all know the fourth one's the most difficult," McQuaid said. "We're going to need our best effort."
