Boston gets: Shawn Marion & Jose Juan Barea
Dallas gets: Rasheeds contract & Big Baby
Why for Boston: Marion is a perfect fit for this ball club. he can give you 20-25 solid minutes off the bench, plays D very well, can knock down big shots, and is the type of player who you want running with Rondo on the fast break. I practically was praying that we were going to sign him for the MLE last off-season.
Also, Jose Barea is a solid back up PG to come in and give energy off the bench. He's a local guy too,and that never hurts.
Why for Dallas: Dallas sheds a big chunk of salary after this trade IF Rasheed decides to retire and get a guy in big baby who plays hard and can help the Mavs with their rebounding issues. Big Baby is a perfect fit for a championship contending team...possibly can be used to lure LeBron in a sign-and trade?
Possible rosters:
Rondo.....Barea.....Bradley
Allen.....Allen
Pierce.....Marion
Garnett.....Al Harrington (MLE).....Harangody
Perkins.....BEN Wallace.....Erden
Jason Kidd.....Jason Terry
Raja Bell(?).....DeShawn Stevenson/Dominique Jones
LeBron James
Dirk Nowitzki.....Glen Davis.....Eduardo Najera
Brendan Haywood.....MLE?
See you in the finals, Dallas

Obviously alot would need to happen but i'd love to see it happen
