Here's a scenario -
Hextall stands pat. Maybe they add defenseman on the right side with some grit. They let Angello/Lafferty/Zahorna fill out the fourth line, give Simon some minutes, etc.
Throughout the season, they build a little cap space with Malkin on the LTIR. Geno comes back, they let him get into a groove, and then they make a splash at the deadline. And maybe that's when they go and get John Gibson and Rickard Rakell from Anaheim. The Ducks haven't improved. They'll be awful. Gibson will be frustrated, maybe even demand a trade. Rakell will be a UFA at the end of the year.
Pens could put a package together that is less expensive than it is now and allows them to get two quality players because they were able to bank some cap space. And they'd still have an improved lineup going into the playoffs.
