This is a trade that I think will benefit both teams. Do not kill me on this one but i really think this will help everyone.
Atlanta gets: ford, Posey, rush
Pacers get: Crawford, Williams
The reason why the pacers are going to do this trade is that they get a quality two guard even if they are just rent him. Williams is a pretty good player. He is expensive, but really he could be a trade chip down the road or maybe fit in as a sixth man.
Atlanta needs a quality back up point guard, Ford is supposed to be on their radar. Rush is in need of a change. Posey is a quality 3 and good to add to any team.
Looks good for both sides and I like this deal.
