Any scenario where we acquire Siakam, while keeping Tatum and Brown, would be a homerun in my book.
I understand the most likely scenario would involve Kemba going to a 3rd team, but you could actually get there with Smart, Thompson, and Nesmith (or Grant, Romeo, Pritchard, etc) in terms of salary. Add as many picks as necessary. I would absolutely LOVE to get Siakam on the Cs.
Our bench would be abysmal, but we could actually trot out a starting line-up of Kemba/Brown/Tatum/Siakam/Theis (or TL). That is definitely championship-level.
