I could see OKC taking Topic at 12... not a fit at all but talented and they don't have a rotation spot for a rookie right now anyway. Its a way to kick the can/asset forward a bit maybe. Might need to move Giddy first.
If OKC let fit get in the way, they may not have Jalen or Cason. They'll take the best guy for sure. I don't think Topic will slip that far though.
I do wonder what the price is for Giddey. I think he's worth a flier if he comes cheap. They could be interested in Kessler too....though I'd definitely say Kessler has more value than Giddey at this point.
