I don't think it did and I have reason to believe little has changed. In all honesty, I think the veterans are less a collective voice of control as they are on their own islands. That's what I read into the report that Fenton went to each of #9, #20 and #11 to get them to buy in and ask that they pull the rope together and in the same direction. I think Parise still wants to win, which is why after the season he looked devastated and is worried he's hitched to a team that is going nowhere and understands the end of the career is within sight. I don't think Boudreau wants to let the vets run the show, but I don't think he has total control either. He was forced to playing Bitetto even though no coach every should've been compelled to play him. If he doesn't have the power to decide who is playing on his 3rd pairing, do you really think he can tell Suter what his ice / power play time will be?
I don't think Parise is making those demands, but he came close with the Adam Oates thing and that did help destabilize Yeo's authority and ultimately led towards the team giving up on him and his firing. So far the team hasn't given up on Boudreau, yet...we'll see if it happens especially if success is hard to come by this upcoming season.
