Wild is a better team now for sure, that's obvious. However, I'm not sure this instantly makes them a Cup contender. They still have some other issues to address. Good for them and their fans. A good day to be a Wild fan.
As someone else pointed out in the other thread, I'm not sure this is going to create a frenzy to get Nash. Certainly not in the East, at least to the point of desperation. In the West, the elite teams probably feel this makes the Wild relevant, but probably not scared of them.
