Still can't see him going. Most teams won't offer more than the MLE, which means he'll either A) have to get some team that misses out on big free agents to give him a big 1 year deal or B) work a sign and trade. In the case of A, I think Boston at least offers him enough in a 2 year deal to overshadow an impressive 1 year deal. And in the case of B, I don't see who would really want Ray at much more than the MLE for much more than a year or two unless they were trying to dump a really bad contract. And if that's the case, why would we want to make such a trade?
With KG around two more years and Ray really not holding the team back from doing much, I don't see why you don't bring him back.
