In thinking about it, worst case scenario for Spurs would be Risacher to ATL, Sarr to Was and Reed to HOU.
I dont see SA wanting Clingan so that doesnt help us in any way conceivably.
However, IF the draft starts with either Clingan, Sarr, Reed or Clingan, Risacher, Reed, then I think that scenario is perfect for SA to trade up from pick 8 to pick 5 or 6 and walk away with either Sarr + Castle or Risacher + Castle.
But if Clingan doesn’t go top 3, then it’s less desirable. I would be happy with 2 of 4: Sarr, Reed, Castle, Risacher.
