99.3 - Percentage of the Capitals' first-round series with Boston which has been played with the score within a single goal through six games.
The games have been tied for 69.4% of the time, the Caps have had a one-goal lead for 26.8% of the time, the Bruins for 11.5% and the Caps held the only two-goal lead of the series... for less than three minutes in Game 5. And, as Caps Today points out, the series "is the first in NHL history to feature six straight one-goal games. Five of the six game-winning goals have come in the 59th minute of regulation or later in this series."
Yep, it's been that close.
