Signing UFAs has nothing to do with a rebuild. Every team with cap space is chasing the same top players and, frankly, I'm not optimistic about Montreal's chances at signing one. Even then, while some UFAs make their team better, they rarely turn them into a contender.
Successful rebuilds depend on drafting top talent and surrounding it with veteran leadership. Our only proven top talent is Suzuki, Caufield, and Dach. Obviously that's not nearly enough. We either to discover stars in our existing prospect pool or we have to find them in the next draft. A bunch of good prospects don't add up to a great team.
interesting that you consider Dach "proven" top talent, but not Guhle... If anything, i'd say that with what we've seen thus far, Guhle is a better bet to be a top-pairing talent than Dach is of being a top-line talent...
and really, both Suzuki and Caufield remain bottom-tier "top line" players at this point, neither has shown the consistency as of yet to be locks to becoming top-tier first line players...
beyond that, I think in looking at players with a good chance of becoming top line talent, our in-house group is larger than you position it...
in the NHL:
Suzuki, Dach
Caufield, Slaf, Newhook
Guhle, Barron
in the prospect pool
Mesar, Beck (both longshots)
Roy, Heinman (both longshots)
RB, Hutson, Mailloux, Konyushkov, Engstrom
the 1st this year and the two next year will add to that pool (or get used to add a player closer to/established already).
imo, we've got the foundation in place so as to be realistically 1-2 UFA/trade acquisitions away from having the right mix of top talent to have ice a contender in 2-4 years
if you look at the contending rosters this year, Colorado and LAK are the only teams being led by top talent drafted high (top 10), all the other rosters (unless you still count the Oilers in... which might be fair as they look to have figured things out, albeit fragile) of top teams are led by players either acquired in trade/UFA or later picks developed internally over time... Dallas, Carolina, NYR, Boston et. these teams are built off of talent acquired through multiple channels, with strong foundations of depth. We're on that path and with assets like Dach/Newhook/Roy/Hutson et. it will take some time to find out which, if any, are able to transition into that elite/top-end category. Only takes 1-2 to really break out (like a Pastarnak or Aho), provided the foundation/depth is strong.
Hughes has been following a pretty clear plan, and shared quite transparently that over the next 1-2 years, leveraging the assets accumulated (including cap space and team culture that appeals to elite performers) to target a major talent is the intention... i'd be surprised if by the start of the '25-26 season, we haven't seen that play out.
Future is bright
