Nope, Devils haven't been voted in yet...
It's too early to know who will graduate first between McKenna and Frazee. Proof that it's a crapshoot between the two is found in the fact that I am more of a McKenna fan and Dobber is more of a Frazee fan. We both have solid reasons for why we feel each of them are legitimate choices for the Devils to develop into what could be the next starting goalie for the Devils.
At the same time, there's a very good chance the Devils acquire a veteran goalie in the second stage of his career. Kind of like what Florida did with Tomas Vokoun. To be honest, there's no way of knowing exactly what New Jersey plans on doing until we know Brodeur is ready to retire. And even that is up for speculation...it could be one more season, it could be three or four.
I would have to think that since New Jersey chose to sign Hedberg instead of graduate either McKenna or Frazee, the organization doesn't think either of them are ready for a more solid NHL role.
My thoughts are that McKenna has better size, more experience and has the ~20 NHL games experience with Tampa Bay. He did very well in that stretch and was able to boost his reputation around the league to other GM's.
One of the determining factors will be their play in the AHL this season. They are set to battle each other for minutes once again. And since so much relies on "what have you done for me lately" then you'll get a really good indication on which goalie is leading the race by how they perform this season.
So to answer your question, I don't think it's worth trying to acquire either of them. But if you wanted to snag one, I would go with McKenna. He might have the upper hand in the eyes of management due to his previous NHL experience with Tampa Bay.
