Ridnour is BYC so any trades for him are extremely tricky.
I would think that SEA might want a draft pick. Indy can't give up their 1st of 2008 (they traded their 1st rounder 2007) and not sure they would for this trade. Would you throw in their 2009 1st rounder for this trade? Would SEA be happy with expiring contracts and the potential to see if Fred Jones and Morris fit their team and have a good shot at resigning them?
With the current situation in NY (Thomas and Dolan), I don't think NY does a trade until they resolve their GM/HC concerns.
