Could Marcus Morris provide spark off the bench like Lamar Odom?  Maybe.  Odom definitly isn't a SF, but he's not a true PF.  For a man with no real position, he still produces as one of the leagues best 6th man players.

They have comparable heights and builds.  6'9"/6'10"  around 230 lbs.  Not an out of this world athlete, but can score the ball in bunches.  They are both aggressive with the ball.

Other than Lamar Odom being a known quantity, would you trade Marcus Morris for Lamar Odom straight up?  Are there any Kardashian sisters available for Marcus to hang out with?
