I think the crazies are the ones who think we are in the finals next year. Our "star" players are 22 yo or less and some not yet in the league! Our defense is not set. Our #1 Goalie is still in college. We are not going to slip a fast one on a team for McDavid. Our big moves will be free agent signings, fringe players and developing our team once our rebuild pillars are actually in the NHL. Suzuki will be close to 30 when this happens which is not a bad thing. I am not pessimistic quite the contrary but realism has to take hold at some point. Look at where Edmonton, Winnipeg, Toronto and Dallas are and how many years it took for them to go from basement to contenders...and they have not won a thing yet.
I think that your timeline and the finer details of your post, probably to make your point, are a bit off. How many star players do the Habs have that are 22 or younger?
Hutson and who?
Yes, Demidov and Reinbacher are not yet in the NHL.
However, the idea that Suzuki will be 30 when the team is competitive and would require final touches is a bit far-fetched as a timeline.
Realistically speaking -- especially if a 2C arrives next season to facilitate the development of everyone, from the forward group to the D-Corps -- four years from now, with two years left on Suzuki's contract (as a 29-yr-old), there should be an opening window for the Habs to win a Cup if all goes well.
Suzuki will be a veteran in his prime, as will be Caufield (28, with three years left on his contract) and Guhle (27, with three years left on his contract as well).
Slafkovsky, in his 7th year at the NHL level already, should be considered a young veteran at 24, all with 5 years left on his 2nd NHL contract.
Hutson will be 24, with four years of NHL experience as a young veteran with most of his second NHL contract ahead of him.
If Laine signs an extension with the Habs, he should be roughly halfway through that contract as a 30-yr-old veteran.
Demidov will be 23 and starting his second NHL contract, with three years of NHL experience behind his belt.
Reinbacher, at 24, should have three years of NHL experience if his health holds up.
Four years from now, Hage should be in his 2nd NHL season as a young player and beginning to have some impact on the results of games for the Habs.
Four years from now is the season to watch out for, IMO, but, to get there in the form required to challenge for a Cup, Hughes needs to get a genuine 2C for next season, in order for everyone to develop as close to their projected ceilings as players.
