Nothing specifically about this trade, but on the ESPN rumors website there is a title that says something like "The Raptors and Gay", then below it says that the raptors reportedly have interest in Gay. (I dont have insider access so that's all I could see)
This is from May 25. Which coincides with the rumor on the three team trade. I think it is safe to get your hopes up atleast a little bit for this trade. I believe there is something going on there.
