Im notsure the Leafs have had a D like Raddysh in 20+ years, a cannon shot. ar least the last 2 years are not full no trade, they can move him if needed.
They need to add speed to the bottom 6, and have a checking line that can handle other teams top lines and not get dummied.
Mikheyev is a UFA, id look at him again, good for 15-20 goals
Mikey will cost in the high 5M range over 4 years to sign him.
