NHL DFS: 3 Lines That Were Unlucky in 2016-2017

Much like football and baseball, there is a lot of game-to-game variance in hockey. That being said, part of being a good DFS player is embracing variance.
In the NHL, a stat called PDO calculates a line's shooting percentage plus their save percentage. Over the long run, a line's PDO should normalize to 100, but we know this isn't always the case -- the higher the PDO, the luckier a line got, and vice-versa.
Here we will highlight the lines that had great possession numbers but a low PDO and/or a high expected goals-for, as these lines could have some positive regression coming in the 2017-18 season.
