The Timberwolves rid themselves of malcontent Rashad McCants while the Kings continued their salary cap purge with their third trade in a week. The Wolves got forward Shelden Williams and point guard Bobby Brown and shipped McCants and center Calvin Booth to Sacramento on Thursday. Williams, the former Midwest City High School standout, was the fifth overall pick in 2006 by Atlanta. He has never fulfilled the promise he showed while at Duke and is averaging just 3.7 points and 2.6 rebounds for the Kings. The opportunity for playing time is there in Minnesota. The T-Wolves have a big hole in the front frontcourt behind rookie Kevin Love. "The future’s wide open for him,” T-Wolves general manager Jim Stack said of Williams. "This could be a good opportunity for him. … We’ll see what he can bring to the team. We’ll be evaluating him as we move along.” In other trades Thursday: →The Magic landed Rafer Alston from Houston in a three-team deal that also included Memphis.
