Additionally, the team won't consider moving a future first-round pick in a rental deal, Friedman wrote in Thursday's edition of "31 Thoughts."
The Leafs already sent their 2019 first-round selection to the Los Angeles Kings for a player with term in defenseman Jake Muzzin, but moving a future first-rounder for a player on an expiring contract is apparently not in the cards for Toronto.
Liljegren was selected by the Maple Leafs with the 17th overall pick at the 2017 draft. The smooth-skating defenseman has been plagued by injuries for much of his tenure with the AHL's Toronto Marlies but he has the potential to become a top-four NHL blue-liner. The 19-year-old's right-handed shot is also a valuable commodity in the league.
Sandin, 18, was the 29th overall pick of the 2018 draft. A sprained elbow has held the Swede to just 20 games with the Marlies this season, but he's picked up an impressive five goals and five assists in those contests.
Both Ron Hainsey and Jake Gardiner are scheduled to become UFAs on July 1. Considering the Leafs' impending cap constraints, they may be forced to fill the void on the blue line internally next season.
