Assuming the Lightning get Karlsson in on a $12m AAV extension, with Miller and Foote / picks heading out to OTT and Callahan to NYR respectively (among I'm sure a bunch of other pieces), they are absolutely stacked up.
RFA salary assumptions:
Brayden Point: $5.3m AAV, 4 years
Cédric Paquette: $1.75m AAV, 2 years
Slater Koekkoek: $1.4m AAV, 2 years
Jake Dotchin: $1m AAV, 2 years
Adam Erne: $800k AAV, 2 years
$1.83m for the Matt Carle buyout
Palat - Johnson - Kucherov
Killorn - Stamkos - Point
Paquette - Cirelli - Stephens
XX - Erne - XX
Hedman - Karlsson
Sergachev - McDonagh
Koekkoek - Dotchin
Vasilevsky
Domingue
That puts them at $78.55m with enough room to add 2 fourth-line JAGs, a 13th forward, and a 7th defenseman, assuming the cap goes up $1-2m again. The silver lining is Sergachev is up after next year but they'll likely just move Killorn to fit him. Fuck.
