Here's one thing to ponder/consider.
With the trade they made, they get 2 2nd rounders and a 1st round pick.
Could that have been the best offer they received for the 11th pick? As in, maybe the offers they received didn't include a future 1st in addition to draft assets in the future AND a pick this year?
I mean, if you told me the options were drafting Kaspar at 11 (which clearly would've been a reach since he dropped to 20th), and that's it VS taking a flier on MmmBop AND get a future 1st plus 2 future 2nd round picks, I'd probably lean towards the 2nd package.
Maybe that was the best offer they got. And maybe that future 1st (in 28) is a safety net in case they have to, at that point, give Chicago the 1st round pick and it means they can't swap with the Bucks.
Maybe no other team was offering what they got, and if that's the case it's probably a smart trade. Takes a shot at a guy who could be a decent player + save them potentially from losing a draft pick in 28 AND accumulate more 2nd round picks to sacrifice to the basketball gods when they finally build a new stadium.
