Indeed, the defenseman had a very impressive first season with the Laval Rocket, and he seems ready to make the jump to the NHL.
Observer Marc-Olivier Beaudoin, who publishes extensively on Platform X and is generally quite credible, has just proposed an interesting trade scenario that would bring Trevor Zegras to Montreal.
The Ducks need a right-handed defenseman, and Mailloux would be the centerpiece of this return. In my opinion, even though I love Trevor Zegras, I believe this would be too steep a price to pay.
The Canadiens won't win right away, even with Zegras in the lineup, and probably not the following year either.
