Free agent center Greg Oden will take meetings with officials from the Dallas Mavericks, Sacramento Kings and New Orleans Pelicans this week in Las Vegas. Per ESPN: “The sitdown with Mavericks officials, sources said, is scheduled for later Monday, as Dallas pushes to join the San Antonio Spurs and Miami Heat at the forefront of the race to resurrect the career of 2007′s No. 1 overall pick. Oden, 25, has battled numerous knee injuries and hasn’t played in an NBA game since Dec. 5, 2009. He is coming off his third microfracture knee surgery in February 2012. He was the top overall pick in the 2007 NBA draft out of Ohio State, chosen by the Portland Trail Blazers one spot ahead of Kevin Durant. [...] Heat president Pat Riley recently told local reporters that he’s had an extended exchange with Oden already.”
