Love the well thought out post, thanks!
I don't love the Ottawa trades because taking on Korpi is rough, He sucks, and goalies are harder to hide than other positions. Definitely a big fan of doing the Seattle trade especially but even NJ since Dickinson will likely be there still. Buffalo trade would be fine but likely trading up for Parekh or Yamekchuk there.
I really like both the Islanders and Blues trades and would do both. Lee could be a good veteran winger to put on a line with one of the Sharks' young centers (and he only has 2 years x7M left on his deal). Krug is a puck-moving defenseman that could be useful on the PP while prospects are developing as the defense currently is lacking any puck movers. Cap space shouldn't be an issue even with Krug having 3yr x6.5M left on his deal. Can always buy out Vlasic or send Burroughs to the AHL if there's a logjam. I think SJ could grab MBN and Jiricek with those extra 1st round picks. Obviously a pipe dream but a Celebrini, Dickinson/Parekh/Yakemchuk, MBN, and Jiricek draft sounds pretty damn nice eh?
