Well, our old friend overtime was back in Boston Wednesday night -- with the Blackhawks outlasting the Bruins 6-5 (OT) in Game 4 of the Stanley Cup Finals.With the win, Chicago tied the series at 2-2. It was the third game of the series that went to overtime.However, with a pivotal game 5 in the Windy City Saturday night, this game was vastly different than the previous three games of the series -- despite the need for overtime.While the first three games were more defensive-minded games, last night was a raucous, up-and-down-the-ice affair. It was fantastic hockey, mixed with a supreme entertainment. If you're being honest, wouldn't you rather watch a 6-5 game than a 2-0 shutout?And just when you thought Bruins goaltender Tuukka Rask was made of steel-cast iron and headed for an easy series MVP award, he actually looked quite human on a night that produced 11 goals.Honestly, if somebody told you the Blackhawks would score 6 goals against Rask -- after his Game 3 shutout -- you would have thought they were crazy."Both teams are so great defensively. Both have great goalies," said Chicago defenseman Brent Seabrook, who scored the game-winning goal with 10:09 left to play in overtime. "I don't know; it was one of those games. They got some goals on the power play, we got some bounces. It was nice to get some past Tuukka..The Blackhawks didn't get "some" past Tuukka They got a whopping half dozen.Of course, the Bruins did a ton of scoring as well. Patrice Bergeron -- who is quietly having an excellent Stanley Cup Finals-- led his team with two goals.The game also turned the series on its ear. The Bruins looked to be in control of the Finals -- and the Blackhawks appeared clueless in terms of generating offensive chances.All that changed Wednesday night -- and it's now a best-of-three series for the Cup.NOTE: The series heads to Chicago for Game 5 on Saturday night. The NHL uses a 2-2-1-1-1 format for its Finals series – unlike the NBA and MLB, which employ a 2-3-2 format. Interestingly, both the NBA and MLB use a 2-2-1-1-1 format throughout the playoffs – except for the Finals. This is a relic from the days of each league trying to avoid too much travel (hence the 2-3-2 format) from east to west coasts. We believe the 2-2-1-1-1 is a far better format than 2-3-2. Playing three games in a row at home is actually unfair to the home team. It’s extremely difficult to win three consecutive games – and the 2-2-1-1-1 offers a better competitive balance. Go ahead and sound off. What do you think?Posted by HockeyFanLand.Image by Bruce Bennett/Getty Images.
