The Penguins currently have a salary cap obligation of about $62.5 million next season according to CapFriendly, leaving almost $21 million in open space to work with. Ideally, the next general manager should look to leverage that even higher by virtue of removing some pieces who have salaries on the books next season via trades or buyouts.
While the amount of open cap space is relatively high, Pittsburgh has significant needs to address with that money. The goalie situation needs to be sorted out with Tristan Jarry or a replacement as a starter- likely to be addressed in a trade.
