Folks are talking about bringing in Lee means Mozgov/thompson have a rebounding advantage, doesn't really matter at this point? What great defense and rebounding are they getting from Draymond and Bogut who are getting bullied anyway, and don't match up with Lebron (who defensively is most important) ? Lee is a better pick and roll guy (which helps curry tremendously) and gives them better spacing to find better shots in the paint or kick out to an open shooter, which is Golden State's MO.
Neither Curry or Clay are major threats at driving to the basket for easy shots/FTs, so as long as Dray Day is making brick houses from 3s (in the PnR), and Bogut doing nothing then Lee (as long as he doesn't get into major foul trouble, that's the big if for him) gives them better spacing and opportunity to pick the pace up.
