Each team went through a major scoreless streak during the series. The Bruins didn't score for a span of 100 minutes and 57 seconds (starting roughly 6 minutes into the third period of Game 1 and ending nearly 15 minutes into the second period of Game 2). This stretch is depicted via the dashed black line. The Blackhawks later topped that, experiencing a scoring drought of 129 minutes and 14 seconds; after scoring at the 11:22 mark of the first period of Game 2, Chicago didn't light the lamp again until nearly 7 minutes into Game 4. This span is shown with a dashed red line.
Another offensive difficulty for the Hawks was the power play; for the series as a whole, they scored on only 1 of 19 instances in which the Bruins had a man in the penalty box (a few times, a Chicago player was sent off at the same time as a Boston player, which would not be a power play).
The most memorable aspect of the series would have to be the closing moments. The Blackhawks led the series 3 games to 2, but trailed in the closing minutes of Game 6 by a 2-1 score. Chicago then stunned Boston with two goals just 17 seconds apart (with 1:16 and 0:59 remaining) to win 3-2. Tom Tango cited an estimate that Chicago had only a 3% chance of winning the game before its late outburst and noted the oddity of both teams being in a position to pull its goalie in the same game (a team down a goal in the closing minutes will almost always bring its goalie to the bench to substitute in a sixth attacking player).
Weird things can happen in hockey (see this video of quick goals), but Chicago's manner of clinching this year's Cup is one for the ages.
