Was keeping Lamar Odom a good decision?

Though Lamar Odom comes at a steep cost for not being an everyday starter, his versatility has been crucial to the Lakers success. He can play three positions(Small Forward, Power Forward, and occasionally Center) which is crucial considering how often Andrew Bynum and Pao Gasol get injured. Also if Bynum or Gasol get in foul trouble, he can substitute into the game for them without the Lakers skipping a beat in executing their gameplan. Also because he can play so many different positions if a certain player on the Lakers is struggling guarding a particular player, they can put Lamar Odom on that player. Overall, his adept versatilty and skill for dribbling, passing, rebounding, and defense, make Lamar Odom worth alot more than the Lakers pay him yearly(roughly 8 million).
