In Kamahl's humble opinion they lost the series because they got dominated on faceoffs. When you lose so many faceoffs you give a huge edge to them possession-wise and it meant the difference in the series, particularly in games 1 and 6 where they were extremely close and control of the puck meant everything.
This game was similar, in that they lost in the circle hard, but every other God damned thing went wrong, too, they gave up a ton of odd man rushes, a breakaway, the Kings' power play was absolutely on point, etc., etc.
Fuck. Hell of a series.
