If Presti brings a le to OKC, I don't think he's going to be losing any sleep over whether he gave up too many picks for Osmane Dieng.
It's the fallacy of being so concerned about winning every trade. At the end of the day, the goal (for most franchises) is to win on the court, not to win trades. For example, if the Spurs only got one FRP for Dejounte instead of 3 (one being the CHA) plus a swap, it still would have been a massive W because it facilitated the main goal, which was landing Wemby.
If Presti wins a le, he'll have accomplished the goal. I'm sure some fans of the Kings or Hornets or Jazz or any other loser franchise will sit around and contemplate how Masi couldn't keep Kawhi or some bull , but they let you hang the banner and keep the trophy forever... who ing cares if you missed out on picking another Malaki Branham as a result.
