Lee, 35, is entering his 15th season in the NHL. The veteran from Minnesota was just one goal short this past season of making it five straight seasons with at least 20.
He's only missed one regular-season game the past four years and gives the Mammoth a great, reliable veteran on the left wing.
Utah finished this past season with a 43-33-6 record. They were later bounced in the first round of the playoffs after losing in six games to the Vegas Golden Knights.
