Mason reacted angrily after the Bucks traded him in 2005. But he says today that he has put his differences with Bucks general manager Larry Harris behind him and is happy to be back.
Two years ago, Mason called Harris a "snake in the grass" for trading him to the New Orleans/Oklahoma City Hornets just before the start of the 2005-06 season.
Mason says now that his comments were just an emotional reaction to being traded.
Harris says there were no hard feelings.
The Bucks are expected to formally announce tomorrow that they have re-signed guard Mo Williams, an unrestricted free agent who was courted by the Miami Heat.
That leaves them with one pressing off-season concern: Convincing No. Six draft pick Yi Jianlian to sign with the team.
