i was just coming to make this same point.
everybody right now is drooling at the prospect of voracek and giroux lighting things up.
but just because the plan is for voracek to play on giroux's wing and just because it seems like a good fit, well, it doesn't mean that it will be.
it might work out, it might not.
if i had a nickel for every time a player got hyped up because of his potential linemates and the results were disappointing... i would be a rich man.

these two are close, regardless of who they play with, but picking a player on potential linemates can be a gamble.
