I think most people in positions of responsibility usually say exactly what they mean to say, and as a "preparation" guy, I think Nil certainly wouldn't be one of the ones to be loose with words, as sometimes does happen.
That said, he may plan on brining them all to camp, giving them all the ops, but has been a GM long enough to let Lindy decide who stays. He also knows there will be maybe one surprise, and more disappointments with young players.
In general, I think he means to say that after years of filling in with older vets as place holders because you don't trust the youngsters, it may be time to build with the youngsters. Under bankruptcy, we were in the place holder mode, but it is not way to build a team for the future. And, we have all the evidence we need - jettison Jagr, Ryder, etc and the team scored as many goals. Trade Roby and go with Dillon, Benn, etc. and while Goli and Daley led the way, our GAA didn't go up drastically.
Young players get better, old players get older. If we are going with a team speed concept, getting a slow Vanek, Richards, Vinny, etc. doesn't seem to fit. The big names may give us a sense of security, but probably not arguably better hockey.
I get the sense that we will end up doing zero UFA deals, or go with a younger, less heralded guy at lower money who will fit in three years from now. Just a guess.
