They need to upgrade the D.
Chychrun would have been the preference (and I wouldn't have a problem moving a D off the roster for him either.) Gio isn't a top pair guy anymore (would be a great 4-6 option) but Lindholm is very good.
Really, getting a few good bottom 6 guys, a top 4-ish defender would be my preferred route rather than trying to land a scorer. Our strengths are goaltending and ST's. If we can turn 5v5 times into a slog fest where nothing really happens for anyone, thats probably our best path to victory in the short term and also probably the easier path to make moves for.
