Why for the Pistons? I don't know! There are rumors they have interest in LaVine, which makes no sense, but in the event they actually are this trade is a buy low opportunity to add a lead scorer and try to turn that shit show into a few more wins. They also get their 24 pick back which frees up flexibility on how they can use future picks in trades as well

Why for the Bulls? Apparently no one else has interest in LaVine as he is currently fighting Jordan Poole for worst contract in the league. Here they clear cap and acquire a 1st. I don't think there will be a better deal out there

Why for the Knicks? We bring home Burks, giving our bench a playmaker for when Brunson is off the floor. Thibs LOVES Burks so the fit is as close to perfect as you can get without depleting a ton of assets
