You have to really get an impact player back if you're trading that 3rd pick in a package. The Butler's, Cousins of the world, etc.
So if nobody's willing to give you an impact player, you keep it. A pairing like Ainge & Stevens would bring an impact player here at 3, IMO. There is no way a pairing like this, misses on a pick this high. These guys know their stuff.
If I had to pick any two guys from this league to be in the draft war room with me, I'd pick this organization & these two brains. I like our chances.
