Not sure I'm a fan of this. Unless the team really doesn't feel like a guy like Mironov can play right now, then why not just roll with the guys you have?
At first glance, I would have to say this :
Bigras - 22 yrs old - 31 career NHL games experience
Lindholm - 22 yrs old - 12 career NHL games experience
Mironov - 23 yrs old - 0 career NHL games experience
That's a lot of 'green'...
With Nemeth having over 100 NHL games played and being a big (6'3") 25 year old, stay-at-home D-Man...I think this is a way for them to acquire some depth. I think they'll rotate him in gradually and quite possibly the worst of the 3 younger guys above could be sent down eventually.
