I'm ok with the Tampa trade, though I don't love the idea of moving such an important player as Severson out for futures.
I'd jump on the Pettersson trade if the opportunity presented itself, big fan of his game and would be perfect to play 3LHD and push Smith out of the lineup.

I like the Talbot signing provided it's only for one year, should bridge the gap for Daws and / or Schmid to become full-time NHLers by 2024 quite nicely.

I don't like the idea of signing Haula, Tatar and Lemieux however.
Haula and Tatar are playing great at the moment but the risk of them slowing down for next season coupled with neither of them being likely to accept one year deals is quite unnecessary for the team to bear.
Lemieux isn't a very good NHLer either and whatever value he brings as an enforcer is fully offset by his limited skillset.
Instead of having Haula, Lemieux and Tatar in the lineup I'd much prefer them to be swapped out for Wood, Boqvist and one bigger UFA name like Bunting, Kuzmenko or Tarasenko.

Yeah TB Does the trade you described in a millisecond.

I'd love to get Tarasenko, just don't know if they can afford him, although could get close if they didn't take Haula or Tatar and just got a 4th liner from the minors and then signed a veteran depth center to the minimum. May also have to go cheaper than Tablot at backup goal. Like Vanecek so far but with Devils goalie luck, think getting a really good veteran backup that can play 30 games is really important since I'm not all in on Schmid yet. Think Wood is gonna get something like $20mil/4 or 5 if he stays healthy and keeps producing and that is a killer contract for a 3rd or 4th liner that takes alot of penalties. I originally thought someone like Van Riemsdyk or Pacioretty to add some size to the Hughes line instead of Tatar but his line is playing really well right now with great chemistry and think they can get him on a one or two year deal. May feel completely different a month from now.
