Okay, so the Rangers are going to take on a contract of a 34 year old guy with a history of concussions and possible mental health issues with a contract for another 6 seasons at 4 million because??? Why would the Wings take 2 rentals for a season that's pretty much lost for the only semi decent young defenseman in Smith and a pick the Wings need. The Rangers are on fire right now. Unless they think they have zero chance to do anything in the playoffs, which doesn't make sense, I can't see them in a big hurry to trade Girardi.
I never said Franzen would be part of the deal for Girardi. While we're talking about him, though, I think you're undervaluing him. Every team wants a big-bodied top-six winger who's good for 20-30 goals. Franzen isn't ideal, but he's not Dan Cleary. A team that needs more offense, maybe something to put them over the top, might be interested in him.
I don't think Girardi gets moved. If he does, it's because he's on an expiring contract. FWIW, his name has popped up in the rumor mill. One source says he's being shopped. Another says the Ducks are interested. There have been other whispers. Am I putting a lot of stock in rumors? Nope. But I do get the sense that things have changed with his situation. More specifically, I think he's less keen on staying than he once was. Five months ago I wouldn't have even proposed trading for Girardi, because everyone assumed he was a lock to re-sign. But now it looks like they might (*might*) lose one of Girardi/Callahan. If I had to pick one, I'd pick Girardi.
Signing him in the offseason makes more sense for us, but I don't see us signing two of the most coveted free agents (my pipe dreams being Girardi and Moulson), so I thought I'd spice things up and propose a trade for him. The hope is obviously that he'd re-sign.
As for why the Wings would consider trading for Girardi - because we need a top-four defenseman. Granted, there's a chance we may not make the playoffs this season, but I'm assuming/hoping that we're at least where we were last season come the deadline: a seventh or eighth or ninth seed, but really much better than that. And that's how I feel about this team. I think we can do some real damage if we can get in. But we need a top-four defenseman.
