I think we'd be fine with sending the occasional double at someone posting up Lillard. I doubt Kawhi or Green are especially adept at dealing w/doubles, and if they're posting up then that means Duncan or Splitter (or both) are off the blocks) and neither is the fastest guy in the world (or will be out at the 3 pt line). Just don't leave Parker or Green open on the perimeter and let LMA occasionally double.
