This is Dubas' cross to bear.
I could suggest many players and solutions, but I would be cut down for saying so.
I get the feeling that many people feel that the team that MGMT has constructed is the way the NHL is going, or the change that they wish the NHL to go. I see teams like WSH, PIT, BOS, CHI, LA, and I see them winning the cup the way teams always won the cup: skill, toughness, goaltending, defensive play, speed, finishing body checks, shot blocking, etc.
I like Tavares signing and would never down play that. So far I see this team as skilled, but soft. That isn't enough to go deep into the playoffs.
Can't have it both ways with either assertion. Can't say with credibility that HFBoards posters are monolithic in their criticism and won't succeed in narrowing you into a distinct category of critic, while narrowly framing the context of some HFBoards critics as monolithic, whatever the subject might be. Same thing holds true with defining latter-day champions as being defined by the kind of toughness that characterized teams from the 70s, 80s and 90s. Nor is it accurate to compare the recent LA Kings clubs and their ingredients of toughness with Pittsburgh's central characteristic as being the same sort of big-bodied toughness that Sutter's club won the Cup with or the Bruins led by Chara and Lucic.
When I watched the Penguins before their first Cup of two against Detroit at The Joe, it was their puck pursuit, TEAM speed and transition game and skill that left me confident to predict they were good enough team to two Cups in a row. Vegas (you mentioned elsewhere) represents a complete anomaly but they share TEAM speed and transition with Pittsburgh.
I would say one thing you've not mentioned is...YOUTH. Our club is young. That is our key players are young. Very young. And throughout last year's season, there were pockets of plays made that demonstrated an ability to A) Persevere through pressure and B) Execute similar pressure in puck pursuit/retrieval and C) Do so for extended periods of time.
And independent of whatever way the NHL is going...When you can construct your center position with the #1 and #7 picks of one draft and the #1 pick of another...you're doing the right thing. Our wings might not be prototypical power forwards and perhaps more information about the players we have might move Dubas to specifically address that problem, but the possibilities we have in Marner and Nylander and now Johnsson should excite any hockey fan given the level of skill they possess and are being centered by...
I'm sure you're mindful as well that it's very, very, very difficult to convince other clubs to trade their young, tough, big skilled defenceman...even if Nylander was the offer. I"m sure you're equally aware of how hard it is to rightly diagnose the Duncan Keith's of the second rounds of every year's Entry Draft...just ask Chicago.
Suffice it to say, I'm always interested in another person's perspective as how best to address the needs of the team. I'd just like the starting point to address the needs that have been met first, in their proper context.
