There does seem to be some room for optimism. Vasy will start the year healthy, and he did look much improved in the later stages of the season. Guentzel on either the 1st or 2nd line is likely to be a large boost for the team, especially 5v5. The bottom 6 looks better this year, and the defense seems better in terms of improving ga/g with the addition of McD.
In almost any configuration of this year's line up, there was going to be one perceived "hole" in the top 6/9, so what they have now is not surprising. JBB could've potentially gone after a couple of ~5 million aav guys(no,.not Stamkos since he signed for 8, sticking to facts here) instead.of Guentzel, but it's clear that Guentzel was his priority as soon as it looked like he wasn't going to extend with Carolina. Trades can still be made or ufa's signed, and as I mentioned a while back as have others, Paul can be moved to the top 6 if needed/that combo seems to work best(provided no one else is added). It wouldn't be that big of a surprise if they run Paul with Point and Kuch and Guentzel with Hagel and Cirelli, at least at the beginning to see how it works.
It's time for Goncalves to get a shot, so him at 3C with Atkinson and Ace could be decent. It will be a bit different, but this team still has more than.enough to make a run at it, especially if JBB does find that one last addition, either over the summer or as they near the deadline perhaps.
