"Nazem is a proven goal scorer and a fierce competitor who plays in all situations," continued Sakic. "He is under contract for the next three seasons and will immediately fit right in as our second-line center and improve our scoring depth. Calle is a young defenseman with upside who has played in the AHL and has also seen some NHL time over the last two years."
Kadri split his first three seasons of professional hockey between the Maple Leafs and Toronto's American Hockey League affiliate, the Toronto Marlies, accumulating 107 points (43g/64a) in 119 career AHL regular-season games and adding 10 points (3g/7a) in 11 playoff appearances.
