You can't build a good NHL team via free agency anymore. Hardly any free agents worth signing ever reach the open market, and when they do they are overpriced. You can splurge on one or two guys to put you over the top, but the majority of your team has to be built from within.
That means the 17-18 team will be built around the veterans that will still be under contract (barring a career ending injury). That's Z, Kronwall, Green, and Ericsson. Possibly Datsyuk if he's still up for it. The team's engine will be Mrazek, Nyquist, Larkin, DeKeyser, and hopefully top six performers in Mantha and Sheahan. Tatar, if he's extended. Ditto for Helm and Abby with Abby being more likely, though I wouldn't hold my breath on either. Roster filled out with guys like Glendening, AA, Ouellet, and some of the other young guys in GR. I would be shocked if Svechy is ready to start the 17-18 season on the big club.
Otherwise you'll have a depth player, backup goalie, etc signed here or there to fill things out. On the off chance a franchise player hits the open market and the Wings make a run at him, I doubt the new arena will make much difference. It will come down to where the guy's wife grew up, where he went to college, how pitiful the Canadian dollar is running, etc.
