Have you seen the pairing lately. Torts is only really comfortable playing Eminger on the left side. Everyone else he prefers on their natural side. We lose Girardi, we have one of worst groups of right handed dmen in the league.
Guess what? Erixon is also LH...
You are too fixated on L-R balance which is a nice plus to have, but I'd rather have better talent than the balance. If we have enough good Ls we can trade for an R if that's a case of a real upgrade (Weber).
Girardi is a great talent, and his heart is unmatched.
But based on innate potential ability (Erixon), or specific need (a fear of God toughie like Scott Stevens) all these other guys are more valuable IMO, than DG, based not only on now, but what they may bring to the table.
Not sure this team needs a sniper. I think a bigger need is a center with the speed and hands to make moves and create offense. Someone who can get into the zone on the PP and make a defender miss with a deke/dangle (no Zherdev jokes, please).
Another guy like that could only help.
But not help as much as a finisher.
Another Richards would be nice.
But what we really need is another Gaborik.
