Personaly I'm not a fan of NA players.
Most likely those guys will be available in the draft next year. I would rather grab young guys who ARE playing and getting playing time - ie. Del Zotto, Perron (even though he's not doin so good), O'Reilly, Hedman, Doughty etc.

I don't know who's available on your wire - I assume most of those guys aren't - but by having N/A players you are limiting your weekly games. Those are players who you could slot in, and get more games per week - therefore getting more production per week, which can help you win.

I doubt anyone will scoop up guys who aren't even playing in the NHL this year.
