For fun, I took a shot at a win-now line-up. Most of you will question some of the veterans but I don't think they are terrible choices when given very little alternatives. For example, Plekanec has a hefty contract and is declining, but Montreal has not much else to give and the contract only has one year left, and centre is definitely a position of value for Vegas. I have Strome in my line-up, but you gotta think Islanders has some sort of deal in place with that wacky protection list. Other choices I valued veteran goal scorers ie. Grabner/Ryan over other picks like Raanta or Methot where similiar players were available on most other teams. They can act as stop gaps until the younger players, and possible new draftees are ready to take on larger roles. All fits under the cap and still has a decent prospect pool not in the starting line-up.
Neal - Strome - Ryan
Cammalleri - Plekanec - Grabner
Perron - Marchessault - Boedker
Pulkinnen - Grigorenko - Stempniak
Etem
Hamhuis - Johnson
Dumba - Bogosian
Van Riemysdyk - Reinhart
McNabb
Fleury
Neuvrith
Grubauer
Minors:
Shinkaruk, Rychel, Dano, Gaunce,
Koekkoek, Ouellette, Subban (G), Theodore (trade)
Again I'm not saying this is the best option for Vegas, but in some scenario where the NHL was putting on pressure to succeed out the gate, this would be my choice.
