Quoting: BsInOttawa
Dude, I'm in Ottawa and a Bruins fan. These are the two teams I follow.
To break it into the two halves that you did:
1. The difference between Kubalik + 2nd and DeBrusk is large. Wouldn't even start to consider that if I'm Sweeney.
2. Forgetting whether the trade is even possible due to cap, the contracts that Norris and Batherson are on - they haven't yet and might not live up to. Carlo is one of the top defensive D in the NHL, and makes less than either of them. Think of him as a bigger, much better Zub. Poitras is running as middle six C on a FIRST PLACE TEAM as a teenager, 1st year of entry level contract. Bergeron was also a "middle 6, 2-way forward" in season previews before their cup win. Poitras isn't Bergeron, but he can hockey.
You'd have to be the pre-cap Leafs or Rangers (ie. money doesn't matter in the slightest, ignore salaries completely) to make this deal, and even then I think it's still in the Sens' favour by quite a bit.
1. DeBrusk is UFA... Kubalik might be worth a 3rd as a rental so this is 2nd + 3rd... How much more you think DeBrusk is worth as a rental? Large seems excessive
2. Batherson is not living up to his contract? Sure he hasn't been one of the biggest bargains in the league like he was pre Dell cheap shot but his cost per point last season was similar as Jack Hughes, Connor McDavid and William Nylander. The guy can score 70+ pts in the right situation (scored 62 pts last season with a rookie, both coming off a major injury, oh and guy who was not really interested to be there)
2. Carlo is great and my post absolutely went in that sense but I don't know how much better he is than Zub... First, they are similar age and have a similar contract (term/cap hit). Yes Carlo is better but probably not as much as you seem to think. Carlo plays on the Bruins, Zub has been playing on the Sens with clowns as GMs and coaches. The fact that Zub is +11 on that team since 2020-21 is actually impressive
2. okay on Poitras, again in the same sense that I was saying. That said, I don't know how to explain without making it a long story (and have a busy day/week) but Norris and Batherson would also look much better on Boston... It's a coaching and culture thing. They are also coming back from major injury. Trading Norris and Batherson right now is sell low. I wouldn't do it at all.
So yes Carlo and Poitras have value (and even DeBrusk as a rental) but the package is Norris + Batherson + 2nd + 3rd (Kubalik)
