Kyle Dubas says his biggest regret is trading Mason Marchment from Leafs to Panthers for Denis Malgin

"The one I regret the most, I've said this before openly: it's Mason Marchment. We traded Mason to Florida. He had come up with us the whole way. We had signed him to a minor-league deal after his overage season in major junior. He was in Orlando in the ECHL for most of the first year, he didn't play for three months, working with the development team."

"Every time I see Mason play, no matter where he is, I just kick myself because we really needed that style of player throughout. Just the competitiveness, the ability to score, the ability to get under people's skin, the physicality, the ability to get to the net, I always kick myself about that one."

"Toronto traded Marchment for Denis Malgin in February 2020 and it immediately backfired. Marchment recorded 47 points for the Panthers during the 2021-22 season, before signing a four-year contract with the Dallas Stars."

Kyle Dubas expressed regret over trading Mason Marchment to the Florida Panthers while he was with the Toronto Maple Leafs. Dubas acknowledged that Marchment had developed significantly under the team's guidance and played a crucial role in winning a Calder Cup. The trade for Denis Malgin did not yield the desired results, as Malgin struggled to produce points. Marchment's subsequent success with the Panthers and later the Dallas Stars highlighted the type of player the Maple Leafs lacked during the Core Four era.
