The NBA has approved a realignment plan that will split the League into 3-divisions of 5-teams each in the Eastern and Western Conferences. The Memphis Grizzlies will join the Dallas Mavericks in one of the leagues' strongest divisions, the Southwest. Also in the Division are Defending champ San Antonio, and perennial playoff contender New Orleans. The change takes effect next season.. Right now, the Grizzlies are just one game out of first place in the MidWest Division after Saturday nights' thrilling overtime victory against Dallas. The Grizz get back in action Wednesday night at the Pyramid against the Detroit Pistons. Tipoff is 8pm.
