I don't think Ainge has ever made a promise. I think he knows the media game well and plays it to his ability. He's been there as a player, been there as a coach, and has experience with them as a GM. He knows the media game and plays it well.
I think he darn well knows who he wants, where that player might fall, and what it takes to get him if he really has his heart set on that player. Royce White ought to thank him, I think Ainge has helped his stock soar here recently. Ainge is eyeing someone, and just playing coy for now.
