The Oilers should be in on Hart - but it would really need to make sense on multiple levels. To be clear, I wouldn't make the below trade, judt trying to think about what it would take to get Hart while moving out Campbell. I think it would be wiser to just stick with Campbell and hope for a bounce back.
Campbell would need to be heading the other way - this raises the price for the Oilers. The Oilers could retain on Campbell to the tune of 20% of his cap hit, 1M/year - this would result in their goaltending cap-hit with Hart this coming season being effectively the same as it would be with Campbell. The Flyers would be saddled with Petersen and Campbell as their goaltending tandem for two years, with Campbell on the books a further 2 seasons.
I could see the Flyers being interested in:
TIER ONE
Holloway
Broberg
Bourgault
TIER TWO
Lavoie
Savoie
Petrov
Tullio
Niemelainen
So, let's make a deal based on the Oilers getting Hart and Cap space and the Flyers getting what they need (top prospects) PLUS the Oilers sweetening the pot to move Campbell out.
To Edmonton:
Carter Hart - 3.979M AAV, RFA with arb rights in 2024
Scott Laughton - 3.0M AAV, 3 years left
To Philly:
Kailer Yamamoto 3.1M AAV, RFA in 2024 (cap dump, Flyers buy him out)
Ryan McLeod, RFA with arb rights (estimated cap hit 2M)
Philip Broberg (former 1st round pick D with high potential)
Jack Campbell (at 3.8M AAV, Oilers retain 20% - 1M/year)
EDM 1st Round pick in 2024 or 2025
EDM 4th Round pick in 2025
Flyers get 3 solid, young building blocks (Broberg, McLeod and a 1st) for Hart + Laughton, plus an extra pick effectively to taking on Yamamoto and buying him out (4th in 2025). Oilers get a no.1 goalie and 3rd line C/W under contract.
The Oilers could then move out Warren Foegele for a draft pick to free up more cap space and replace him with a UFA winger / cheaper option. This could be Bjugstad on RW at 1.75M. Third line next season could potentially be Holloway - Laughton - Bjugstad.
The biggest issue here is that their are much cleaner deals for the Flyers if they move Hart.
Winnipeg, Toronto, Ottawa, L.A., San Jose, Carolina, NJD and Montreal (just off the top) could probably all make a deal that doesn't require the Flyers to take on any baggage.
