I"m 100% on board with getting Melo and getting Melo now.. I am however with Metro and KBlack in that i don't want to trade Gallo and Randolph. As much as i think Randolph is going to be an all star i'd probably rather trade Randolph because at this moment we know right now that Gallo would fit in perfectly with Melo and Amare because he can shoot the three and spread the floor. If we traded Gallo and kept Randolph i wouldn't be heart broken but we'd lack outside shooting.
The only way i'd consider trading Gallo and Randolph is if the trade really expands. And we get back other talent from Denver. Something like a JR Smith.
Not saying i would do it but you could trade Curry, Gallo, Randolph, and Buike for Melo and JR Smith.
