1. The Halak signing easily stole us the extra 7 points in the standings to get us home ice. Backup goalie is the most under appreciated position on an NHL roster. Sweeney saw that and addressed it.
2. The Lucic trade was absolute larceny (DeBrusk, Frederic, Colin Miller & Sean Kuraly). Might end up being one of our best trades in the last 20 years, behind the Kessel deal.
3. The Charlie Coyle/Mojo trades immediately gave us a legitimate 3rd line. God help us if we didn't address that at the deadline. We probably get bounced in 5 with JFK, Frederic, Backes or Kuraly as our 3rd line center.
I'd argue that if none of those 3 things happen above, our season is probably over right now. Sweeney should get the credit for that. He's also made some mistakes, but at the end of the day, we have a legitimate shot at a Cup Final this year and a lot of it has to do with the moves he's made over the past 12 months.
