I think Patrick Williams is worth two picks in the 20's and I think it would take that for Chicago to even consider moving him. I like his shooting touch and think he'd be a great fit. He makes under 10 million, so more salary is needed which is why I included Caruso who is a lesser version of Brogdon. Those 2 make less than Brogdon this year, which gives Boston a bit more wiggle room as well.
I think you just made the point others are trying to make. If Patrick Williams is worth 2 picks on his own (I have my doubts on that), and Caruso is filler, we are essentially giving Brogdon away for nothing. I see Brogdon alone as having more value than PWill. Caruso is filler. Add in a second round pick in 2030 if needed but not two near term firsts.
I was commenting on the post about attaching 2 1st's to Brogdon. It wasn't because Brogdon was bad it is because Williams is 21 (almsot 22), a prototypical stretch 4, that is a better career 3 point shooter than Brogdon. I like Williams a lot and think Boston is better after making that trade both this year and long term. He also isn't hurt, on the wrong side of 30, and with a big contract (this year anyway). I like the rotation better with Williams
Starters - White, Brown, Tatum, Porzingis, Rob
Rotation - Caruso, Pritchard, Hauser, Pat, Brisset, Horford
Deep Bench - Banton, Scrubb, Davison, Walsh, Kornet
To me that is a better team with less holes on the bench. I worry a lot about Zinger, Rob, and Al staying healthy and having Pat lessens some of that risk, and I absolutely expect Brogdon to miss 20+ games, since he always does and ended last year hurt. Remove the injury risk, add a great shooter at a position of need and it seems like a win win to me. Especially a young uber talented player (there is afterall a reason he was the 4th pick in the draft, not that long ago).
