OEL makes an 8.25 million dollar cap hit until he is 35, and he is 29 (older than our core) now.
Any deal would have to involve a cap dump heading back to Arizona, or failing that some major retention.
Ekman-Larsson also has a higher salary coming up compared to his cap hit, and Arizona is already pushing at the upper extreme of the cap with 3 UFAs (Hall, Richardson and Soderberg) and 3 RFAs (Fischer, Hinostroza and Lyubushkin) pending (Hossa's "LTIR" cap hit is included as part of Arizona's cap hit for now, it will come off the books when the season starts). My guess would be that the saved cap hit would go towards Hall, but I can't see them wanting cap hit back.
OEL is also a LD, and we're covered there as far as I can tell: Edler as our elder statesman, and still a top four, Hughes is our present and future number one, and Juolevi, Rathbone, Benn, Teves, Brisebois, and knowing us, a random UFA or university signing, are fighting for our 3/4 LHD spot. Green hates playing D on their off side.
I'm not seeing a fit here. Even if, asset wise, Arizona gives us a screaming deal, I'm more concerned about the fit on this team. Do we move Edler? Did we premier Juolevi to showcase him for a trade? Is Rathbone not part of our future? Do we have a parallel deal in place for Hughes?
