With Dallas not having a true 2 guard, if they resign Butler, he will have to be that player. With Rudy Fernandez coming off the bench and being not only a young player, but also a proven scorer, this fills a true need for their team.He is not only a great scorer, but gives them the size they need from a guard, and a player other then Stevenson to play and guard other 2 guards. Another thing about this trade is now they don't have to resign every free-agent they have i think they could afford to let Peja Stojakovic go( being a Mavericks fan i hate to say it but i believe it's true). With him coming off the bench they would have, JET, Fernandez, Haywood, Beaubois, and if they can resign J.J Barea and DeShawn Stevenson they could also be there as well. This would possible make Dallas' bench the best in the NBA. I personally don't think they need to get Dwight Howard, although he is phenomenal, i think Haywood, and if they can resign Tyson Chandler and Brian Cardinal i think there okay. So overall i think this was a great trade.
