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?
