Here is framework for you
To
C Austin Matthews (50% retained on this coming year by Hawks)
W Mike Hardman (Just contract dump from Hawks, could be cheap #13 F or play in AHL)
To
C Quinton Byfield
W Adrian Kempe
D Sean Durzi
Kings 2025 2nd (Becomes 1st if Kings make it to WCF next season)
To
G Cal Petersen (2 x $5M)
D Sean Walker (1 x $2.65M)
C Alex Turcotte
Kings 2024 1st
Kings land Matthews at 50% for coming year while signing him to extension this summer and unload Petersen/Walker allowing them to sign Gavrikov while also either bringing back Korpisalo or looking for another option in goal to be #1 via FA/Trade
Leafs get a goal scoring winger (35 + 41 goals the last 2 seasons) signed at nice value for next 3 years, Young NHL C in Byfield, A young NHL RD in Durzi and a pick in 2025 draft that has potential to become 1st round pick
Hawks eat 50% of Matthews cost this year while taking on Petersen + Walker contracts. As compensation they get 2024 1st + Turcotte who gets his chance as Hawks #2C this coming year to prove if he can finally get his career going after all the injuries.
