well, I do expect the Spurs FO entertaining ideas like the mentioned one, because THAT'S THEIR ING JOB.
doing their homework doesn't mean that they will eventually pull the trigger on this ideas.
people here tell all the time, that this is a very weak draft, right? so, a number 8 pick in this draft doesn't have the same value than in most other drafts, right?
so why get crazy over the (theoretically) scenario to use the pick for a trade up deal? and comparing trades in different drafts, as if thoses were precedencial cases and would determine pricing of the future, won't get you nowhere.
I tried to make a point about Risacher some weeks ago, to not just look at the player, but rather look at the cir stances. If Wemby would be happy to get Risacher at his side, a #8 pick in a allegedly weak draft is probably a small price for an important move regarding bonding your superstar to the franchise. (it's no secret how close the ties between the Risacher and Wembanyama families are).
Spurs might see some more reasons why they might be willing to trade the #8 pick. that is roster spots, cap space, free agency and future fexibility. so it will be a weighing up choices and in the big picture the trade up scenario might win, even if the talent you trade for doesn't look like a can't miss opportunity at first glance.
