If Parise and Suter either re-sign with their respective clubs (higher chance of Suter re-signing than Parise, but...) or have their rights traded and sign with their new clubs before July 1st, then there's always a chance that will happen. I think everyone admits that there's a pretty steep drop in available talent after those two.
I think the likely outcome if that were to happen is for Kenny to shift his priorities to finding ways to improve this team in the trade market.
This is my biggest concern by far. Given the apparent likelihood of them hitting UFA and their elite status, there's no way the Devils and Predators don't dangle their rights to get something in return before than walk. Then its a bidding war for first crack at the bidding war. Obviously there is no guarantee either would sign with a team that obtained their rights, but it is a huge advantage (over a week between the Draft and July 1) and one would think a good gesture in the eyes of the player.
I think Kenny HAS to be aggressive and make a play for the rights of Parise (preferred), Suter, or both at or before the draft, else he's taking a high risk of getting to free agency with no game-changers for a team that sorely needs one. If the Wings do get first crack, I have no doubt they would sign before July 1 and probably a good deal cheaper.
