They cannot add in any meaningful way. And they aren’t a middle six winter away from contending. They are several large pieces away.
Been watching this discussion as well. NB are a decent mid pack team this year which is pretty good considering they went all in last year. Whether they buy, sell, or stand pat, I don't see them finishing higher than 5th in the East (or lower than 7th) and they will most likely a have a first.......maybe second round playoff exit regardless. They also hold one or two of the biggest assets in the league outside of Owen Beck. Nelson is 100% gone next year, Dom most liekly as well. They could fetch a Mintyukov type return of picks that can be used as currency for years to come.
So ask yourself, do they cash in on those assets now to set your team up for success for the next 3-4 years? Or do you want to keep those players for just 3-4 more months of service and have them graduate with nothing to show for it? Even if they try to buy, this is still just a good team, not a great team, and certainly not a championship team this year. Your entire top line, which is one of the best in the league should all be returning next year, so the future doesn't look too bad at all. Hamilton did a sell and mini rebuild smartly, I think that is a good model to look to for teams in a similar position after a "go for it" year.
