Rudy Gay and DeMar DeRozan - teammates soon?

A couple days late with this news, but apparently the Memphis Grizzlies have had some scouts in attendance during the last two Raptors home games. Rumour has it that the Grizz are still trying to find a new home for youngster Hasheem Thabeet. I mean sure the Raptors might need a true centre, but should they seriously consider a raw prospect like Thabeet? And at what cost?
