On the surface I would call this a scoring series, but Huet might have something different in mind and Philadelphia isn't exactly an offensive powerhouse. That said there could be a number of high scoring games in this series. Pretty even match up, but Philadelphia has a much better special teams record.

All the non-percentage numbers are scoring rates. For example on the first row, the Washington Capitals have an even strength scoring rate of 2.63 goal for per hour. [GF = goals for, GA = goals against Exx = expected xx, SV% = shot quality neutral save percentage].
In the power play section in order to calculate the expected scoring rates I multiplied the goals for rate of one team and the goals against rate of the other and divide by the league average in order to get the expected rate for these two teams combined. So for example, the Washington Capitals have a power play goals for rate of 7.13 and the Philadelphia Flyers have a penalty killing goals against rate of 6.26. So 7.13*6.26/6.5=6.86 [league average is 6.5].
Outperforming expected goals for is a sign of a lucky team. Outperforming expected goals against is a sign of either a good goaltender or luck as well.
Each category listed has a different importance to winning, so be careful how you read these. Being able to score short-handed isn't going to win a lot of hockey games.
