Cup or bust. This isn't a young, building team. It's got some young pieces and Sweeney's done a better job than I expected at improving the team on the fly, but its top 2 centers are 36-37, one of whom happens to be a generational, culture-setting captain, and as others have noted, the cap is going to bite next year one way or another. I think the team can still be very competitive next season, but this right now is its best chance. This is the best roster they're going to have for quite some time, this is the year they've loaded up before the deadline to an extent that they're simply not going to be able to repeat in 2024, this is the year they've put all their chips in the 'win now' bucket.
As I've said in another post, much as Sweeney's obviously given up some of the team's short-term future for this run, I don't think he's yet placed it in too deep a hole in regards to its competitiveness going forwards. The team is not facing Blackhawks territory and has done considerably better at riding through the end of an aging core and into the next era than the Pens. But in the end this year is still as good as it's going to get and when you've had a regular season this dominant and when you look at all that's taken place and all the decisions made, then there can be only one outcome that's regarded as a success. We as fans know it, and more importantly the players know it. They are either going to attain the ultimate glory, or one of the most bitter of defeats. Hopefully it's the former.
