Mailloux, Dvorak, and a 2nd for Dubois, let's go !
Dubois is not "necessary", however he'd be a great add.
Dubois per se is not a do-or-die acquisition.
However, TALENT is a must-add.
The problem is that it is not always easy to acquire talent if the player does not want to play for you, and even if you do trade for him, results may not be best.
So when a player that HAS talent DOES seem to want to play for you, he is a more promising target.
Look at how Matheson and Petry, with probably similar talent levels, have performed much differently for Montreal the past two years. Matheson is totally engaged. He makes some mistakes, but he IMMEDIATELY fights to correct them. Petry last year, not so much. Different energy level and commitment.
So Dubois is a good target because of all the circumstances. His production, top-6 level, and on the upswing. His age, 24 to finish this season. Versatility, can play LW or C. Size, can complement some of our smaller skilled guys. Contract status, a big one - Winnipeg is losing some of the leverage they have in him as he approaches his UFA status.
I think due to all the above, starting with the clear need to acquire talent, it's worth making the effort to get Pierre-Luc Dubois before we are competing with 30 other suitors.
The cost to acquire PLD is probably going to be less than to acquire 90% of other similar talents. Let's not make the mistake of risking a potential deal while we try to rely on a UFA solution instead.
