Not satisfied with the makeup of a team that was one game from the NBA Finals, Heat president Pat Riley is considering making significant moves that could include trading swingman Eddie Jones and acquiring Memphis point guard Jason Williams, according to several NBA sources.

Among the moves being considered is a trade that would send Jones to Memphis and bring Williams and small forward James Posey to Miami.

Williams played three years with the Sacramento Kings and four with the Grizzlies, earning a reputation as a talented but troubled player. The Grizzlies have been trying to move him all offseason. However, Williams is among the best passers in the league, can run both a fast break and halfcourt offense and is a three-point threat.

Posey is a quality defender with a versatile offensive game, but he spent much of last season battling nagging foot injuries that limited him to 50 games.

Jones was the Heat's third-leading scorer last season and best perimeter defender, proving his worth during last year's run to the Eastern Conference finals. But trade rumors have surrounded the 11-year veteran since his first year in Miami.
