The why for each team

Detroit: Losing Stewart is a hit but same time you get Collins on a 2 year deal. You bring in Kennard which will help the team with 3 pt shooting. You fullfill your obligation to Knicks and get your pick back(basically getting the Grizzlies pick and swapping it to the Knicks for the Pistons pick back).

Grizzlies: Slight move down in the draft but get a young bigman in Stewart.

Knicks: You essentially trade the Pistons 1st and the Mavs first for a top 10 pick

Jazz: Trade Collins on a 2 year deal for Brogdon on a 1 year deal.

Blazers: Go from #14 to #24 but get rid of Brogdon saving them 22 mil and getting them farther away from the luxury tax
