These are always very surprising statements because Mailloux is a much more offensive defenseman and, importantly, a right-handed shot.
Unfortunately, Mailloux's past has caused his value to drop, but it's not the only reason Struble's value might be higher.
Jayden is a very solid, mobile, and athletic defensive defenseman. It's currently a trend in the NHL to have a defenseman like this, especially for the playoffs.
Indeed, he says that Jayden Struble would be almost enough to acquire the next Alex Newhook, and he is targeting Alexander Holtz from New Jersey.
