It takes him to age 34 in the final season at a salary that is reasonble for a top-6 player. He doesn't have the style of game like Backes or Foligno where you can almost predict a fall of the cliff. I suppose he could be less effective in the last year or two, but the Bruins have had good success with both Krejci and Bergeron being highly competitive players in that same age range as Karlsson will be.
If Hertl is a no go, and you don't like WK, who is the guy for you? Note, Giroux is the same age WK will be at the end of his contract.
My issue with acquiring Karlsson isn't concern over physical degradation. It's a big contract, more long than big I guess but $5.9M is a lot in a flat cap world. Grabbing him on the fly and putting your flag in the ground that he's 2C or even eventual 1C is a big gamble. To me, given the retool coming especially two years from now, having Karlsson and Coyle at $11.15M for the next four years after this isn't the position I'd like to see the team in.
Short term, as in this year, there's no guarantee Karlsson fits with Pasta and Hall at a much better rate than Haula. But let's assume adding him and moving Haula to LW is a decent upgrade. On paper, of course it is. But do you think a move like that - which eats up a lot of our deadline space - puts us that much higher in the pecking order? I don't.
In the long term, I just don't think he's guaranteed to be a good enough player that it's worth having he and Coyle paid that much for 2C and 3C. If we didn't have Coyle, different story, but I don't like that move.
I know I'm a bit different than most here in how I would like to see the team progress. I think short of adding something ridiculous, we're going to be decent underdogs in the playoffs. The East is a meat grinder. I'm 100% for Giroux - but I'm not so sure putting him at 1RW isn't the better play. Hertl - of course, and I'd give up a lot to get him with an agreement to resign. But Hertl is several clicks above Karlsson as far as talent goes.
I don't really care for the rest of who's been floated at C so far - and that includes JT Miller - for the prices they're talking. I think the Bruins are going to go as far as Bergeron/Marchand/McAvoy/Pasta/Hall can carry them. Along with our netminder - who I really hope is Swayman by the time the playoffs come around.
If there are other names available - and there will be - and they're shorter term and/or much higher talent, I'd look at it. But I want them to add without sacrificing Lohrei/Lysell/Swayman/Harrison or their firsts in either of the next two drafts. Debrusk, lower picks, lower prospects like Studnicka and Ahcan I can get behind. I'd give up Lysell for a signed (agreed to sign) Hertl, but that's about it so far.
