The Maple Leafs acquired Barrie, the highest-scoring defenseman in Avalanche/Quebec Nordiques history, with forward Kerfoot and a sixth-round pick in the 2020 NHL Draft in a trade with Colorado for center Kadri, defenseman Calle Rosen and a third-round pick in the 2020 draft.
Barrie scored his first goal of the season in a 3-1 win at the Arizona Coyotes on Thursday, when the Maple Leafs ended a six-game winless streak (0-5-1) in the debut of coach Sheldon Keefe, who took over on Wednesday after Mike Babcock was fired.
Barrie, who played eight seasons for the Avalanche, has eight points (one goal, seven assists) in 24 games for Toronto; Kerfoot, who played two seasons for Colorado, has eight points (five goals, three assists) in 21 games.
Kadri has 15 points (seven goals, eight assists) in 22 games for the Avalanche, who are 5-2-0 in their past seven games. Kadri played his first 10 NHL seasons with the Maple Leafs.
