I've watched every single Laval Rocket game the last couple of seasons, and I disagree with you on this.
I personally think David Reinbacher has been Laval's best defenseman basically every game he's played in the AHL, and that he's much more pro-ready than Mailloux
But that doesn't mean I think Logan Mailloux is a bad prospect too, because he isn't.
Just, I've seen fairly little progress defensively from Mailloux this season and that plateau-ing is the opposite of what you want to see in a young prospect.
Development isn't linear, and maybe next season Mailloux takes giant strides forward. But for now I think Mailloux still has work to put in to get his defensive game in order before he sees a lot of NHL icetime.
We don't want Mailloux to "Barron it", and basically flatline his progression because of early-NHL time and trying to cling to his NHL paycheck some way, somehow.
I'd much rather we graduate Reinbacher next season, whilst giving Mailloux even more minutes next year in the AHL, PKing and eating the most minutes he can defensively so that he'd be ready to integrate the NHL team for 2026-2027.
