It's a risk, but not a big one as he is a UFA, but I think Torts could bring something good out of him. To be honest, I don't know enough about St. Croix to say. I've only read things pro and con and have never actually seen the kid play, so don't feel comfortable answering that.
I don't see the Preds trading another first rounder
Why not? Nashville has a deep prospect pool and wants to win the Cup. The Sharks traded their 1st round pick the last 4 years in an attempt to go for it all. All their acquisitions have played big parts in them making pushes towards the Final.
2008: Brian Campbell
2009: Dan Boyle
2010: Drafted Charlie Coyle
2011: Brent Burns (pick along with Charlie Coyle)
I see nothing wrong with Nashville trading 1sts as long as these players make big impacts in getting them far into the playoffs.
This is certainly the year for Nashville to go all in. However, I would hate to lose Halischuk. The kid has 12 goals and is a +7 playing 3rd/4th line minutes. He also hustles every shift. AK would make us better, though.
