Trouba's usage is the key concern here. Not whether or not he likes WPG, which we have no reason to believe he doesn't.
Trouba is obviously aware he will play LD in WPG. And he is obviously aware that Buff is going to get the prime PP usage.
Trouba finishing his development curve at LD instead of RD is bad for his contract after this one. Trouba not getting to put up lots of PP points is bad for his contract after this one.
Trouba's camp is going to want to compensation for that, and that is the obvious spot for an impasse. Trouba won't want a bridge, because he is taking a bridge in a situation that is going to depress his value. And on a long term deal, he is going to want something closer to Ekblad than Hamilton, because his two way upside is closer to Ekblad's than Hamilton's and, playing for WPG isn't going to give Trouba the usage to optimize his next deal. Obviously, a lot on the WPG will change over the next 7-8 years, but Buff being #1RD won't change for a long time.
Now, of course Chevy is not afraid to tell players to pound sand. So now its about blinking. The fact that both parties are being quiet with the media implies, to me, that both sides want to see something signed. The fact that there doesn't seem to be a great hockey deal out there for Trouba, and Chevy's history with Kane, makes me think that its Trouba that will do the blinking... but then you look at Overhardt's history and it all gets very interesting.
In the end, they need to find a middle ground on a deal in value between Hamilton's and Ekblad's and I suspect they will, as at this point Chevy is not in an ideal place to make a deal that is good to WPG. If, for some reason, it does get to the point where Trouba is dealt, it won't be for something that gets the WPG fan base happy.
