I'm not sure how I feel about the Raptors giving Fields an offer. It's only going to be worth it if they land Nash since the entire purpose is to fuck over the Knicks in getting him (without Fields, Knicks cannot make a sign-and-trade with the Suns for Nash, and the only way to make one is to pay more than the Raptors are overpaying). Fields is not good enough for the salary he was offered and if Nash signs somewhere else everytime Fields is on the floor he'll just remind us how BC fucked up big time.
Regarding Nash, I'm not even sure the Raptors are the front runners anymore. We can offer the most money, but Nash wants to win a ring. He's already said he knows the Raptors won't be winning the championship in three years and that he doesn't want to go to a team with the sole purpose of winning a ring (*cough*Miami*cough*). The team that makes me nervous is the Mavericks, because I know the chance to team up with Nowitzki again would be really appealing and joining them will be the best chance Nash will have to win without joining a team like the Heat. Unless the Knicks pull out some sort of miracle with Fields, I'd say it's between the Raptors and Mavs right now for Nash, but imagine the slap in the face it would be if the best Canadian player in history decides that even he doesn't want to play in Toronto.
