I think that DeBrusk, Ullmark, Wotherspoon for Lindholm, Korpisalo, Zadorov is at least a push in the regular season and an upgrade come playoffs when you take the goalies out of it.
But what will decide the season is Poitras, Lysell, Lorhei vs Heinen, JVR, Gryz. And for that…who knows.
It's a bit crazy but since mid-Feb starting with Steen's demotion and Brazeau's recall, Sweeney has overhauled a large portion of his roster. Lohrei was recalled a few days later and then Forbort goes down.
Out - Ullmark, Forbort, Shattenkirk, Gryz, Steen, Boqvist, Lauko, Heinen, JVR, Debrusk
In - Korpisalo, Lohrei, Peeke, Zadorov, Brazeau, Kastelic, Jones, Elias Lindholm, Poitras, and possibly Lysell.
I'd say the general assumptions is they are bigger and better on D (and better equipped for playoff hockey), deeper up the middle both offensively, defensively and on face-offs. Bigger, younger and faster on the wings. This is a relatively young team all things considered.
The two biggest questions are:
1) Do they have enough goal scoring and play-driving on the wing? The past 3 seasons, roughly 290 goals was a Top 5 offense. If they can get 220 goals from their top 10 scoring forwards, they would need 70 from the remaining 3 F and 7 D, an average of 7 per player.
2) Can Korpisalo live up to his contract and provide them with solid play for 27-ish games, including 9 back-to-back situations and a heavy schedule down the stretch (25 games in 53 days)? Call it 16 wins, 11 loses. If Swayman keeps up his career win % over his 55 games, 16 wins from Korpisalo should get the Bruins to 50 wins and 50 wins essentially is a guaranteed playoff spot.
I think Korpisalo holds up his end. We'll see how the goal scoring situation plays out.
This franchise has been built and has bet on strong goaltending and a commitment to strong team defense. The Bruins have been Top 5 in GAA for 7 consecutive seasons I'd be blown away if that is not the case again next year considering the investments on D and C.
Even the 4th line should be more reliable, the Bruins basically didn't have a 4th line until January of last year. More 4th liners who can kill penalties should ease the burden and improve the PK. A reliable 4th line means more defensive zone starts for them and less for everyone else freeing up offensive lines for more offensive zone starts and trickle down effect on the offense.
