If we make the playoffs, they absolutely should forfeit the pick this year.
Assuming any two drafts are of similar strength and tiers, a pick one year earlier is more valuable, but I don't think that value justifies the potential downside.
They don't need not having our first looming over the team during any draft, let alone the Gavin McKenna draft. The odds of us getting a top 2 pick in the 2026 draft are not high, even if we are bad, but the negative marketing potential of the fans even thinking it is possible let alone it happening doesn't justify getting a 1st round talent one year earlier.
The other factor is that they aren't allowed to wait and see how the draft plays out. They have to give up their pick before the draft. So even if they have someone in their top 5 or 10 who slips to 16-32, like Cole Beaudoin was rumored to be last year, they can't decide at the last minute to keep it based on a top 10 talent falling to them at 20.
With the Brady pick, it was conditional, so Dorion had up until Montreal picked to decide if he could keep it. This made it a lot easier for Dorion to play, because if Brady was taken in the top 3 and they didn't have any of the other prospects as highly rated as Brady (who they apparently had above everybody but Hughes the next year), Dorion could have given up the pick. Luckily, Brady was there at 4, and say what you want about Dorion getting them into that mess, he and Mann made a very difficult franchise altering choice to keep the pick.
