Since Plekanec is not on the team, I guess this is for 2016-17? In that scenario, Lawson will be 33 years old, I guess you figure he'll be a late bloomer? Not sure you'll be able (or want) to hold on to a 30 year old Desharnais and a 29 year old Engqvist as spares, assuming they've been good enough to stick in the NHL over those 5 seasons.
I assume you're forecasting this lineup as if every prospect reaches his absolute top potential, and that you realize that is not going to happen in reality. Even so, expecting Leblanc and Kristo to be key parts of a 1st line is unreasonable. If one of those players manages to make himself part of a top line, it will be as a compliment to a star or two.
Because they're older, though I would include Pleky in any plan less than 5 years away. Anyone else, amongst the older players, I wouldn't include (Cammy, Gionta, AK, Markov)
Yeah I understood that form the start, but I was thinking that Plek and Cammy are definitely not too old to be included in a 5 year away line-up. Plenty of players play up to 37-38. I see no reason to believe there will not be 15 seasons vet left with the Habs in a few years.
Other posters even refered to it as 2013-2014 season. I don't see why a guy like Gionta wouldn't be playing anymore in 13-14, even a guy like Moen could still be around (although it more then likely that he won't), but the guy isn't 30 yet.
