Two teams with cap crunches we need to be looking at are LA and Boston. Both teams have LDs that could be hitting FA in Orlov and Gavrikov, both would be huge upgrades for us.
With LA, I think Viktor Arvidsson could be had for pretty cheap as they need to re-sign Vilardi. I was massively impressed with his two way game in the Edmonton series, and he was a big part of some timely goals in the series as well. Having him, Rakell, and Rust would give us phenomenal depth down the right side.
As for Boston, it sounds like they're trying to keep Bertuzzi, but he could still end up in FA and be a target if we decide to let Zucker walk. There are also guys like Hall, Debrusk, Forbort, and Frederic who could be potential trade targets. They also have their obvious goaltending situation, but I personally think both Ullmark and Swayman are wearing Boston sweaters until Ullmark's contract is finished.
