Why not?
I think the habs could easily have 3 balanced lines that contribute to the scoring.
For one, Desharnais has never been tried at wing, so anyone who says "he can't play wing is just talking out of his as#. Two, Plekanec just as easily could be the odd man out at center, for the simple fact that he makes 1.5m more a year and has never proven to be a clutch performer. Neither has Desharnais of course, but i still will continue to back his chemistry with Pacioretty and his slick playmaking skills. Yes, i agree that Briere, DD, Plex, Gallagher, Gionta makes for a small top 9. But if Gionta and Plekanec were replaced with more size, I don't think anyone would consider us small anymore.
Imagine this for instance say next year (forgive me, i always get the left/right wings wrong):
Callahan Galchenyuk Briere
Pacioretty Desharnais Bourque
Gallagher Eller Setoguchi
Suddenly, in a lineup like this, DD doesn't look so out of place.
*Those free agents could be anyone else, i just used guys that have decent size and skill, it could be one of our own guys, or a player we get in a trade.
I get that people want DD gone, and i understand why. But there are other routs that can be taken. Personally, I'd much rather have a more offensive center like Desharnais at 3.5m, than a more 2-way center in Plex at 5m, especially when you consider the eventual contracts of Subban, Galchenyuk, Eller and Gallagher. Maybe its just because i have faith that DD will have a bounce back season, and that I think Plekanec has plateaued as a player, which is to say 50-60 points, so-so on the PP and not great in the face-off circle.
I guess I'm playing devil's advocate here, but Plekanec is not as fantastic a player as people make him out to be. Sure he's the best defensive forward on the team, but i don't think thats saying a lot when you look at all the young guys we have. He often takes ridiculously bad penalties, is not a great a faceoff man, and is not exactly what you would call a clutch performer. He's also created very little chemistry with anyone on this team since Kovalev and Kostitsyn left. And yes chemistry is a big deal, no matter good you are. Everyone's said that Plekanec always got the short end of the stick with getting good linemates to play with, but maybe there's a reason it hasn't happened or worked out with any of them.
Just saying, when you take the whole size question out of the equation, maybe Plex is the odd man out.
