Lee has only seen 18mpg in the 10 games he's been back and has almost the same exact averages as Brandon Bass.
Draymond Green has snatched the starting gig away from him (easily).
With Green needing a new contract this summer and likely a large one, would GS pay a future 1st to move on from Lee and pick up two players who could certainly help with their playoff run?
David Lee is due about $30mill over the next 2 seasons.
