They had 90 goals in the regular season, Jarvis injured his shoulder even more when he went into the post months ago and hasn't been the same since. Svechnikov has tried to be more of a playmaker in the playoffs and if Aho and Jarvis could handle the pucks a little better it'd be a much different story. Same going vise versa with them to Svechnikov, they always seem to be an inch off of connecting and making a play.
Not totally sure what it is but they've been playing good defense for the most part as a line.
