Hawks: Get a cutting big lob threat to pair with Okongwu is big help to there depth. Its simple this is a move to stop the mediocrity and rise to a level of the Pistons.
Nets: Get four first and a top ten pick this year puts them in good position to tank. It also allows younger Nets to flourish.
Warriors - There championship window is closing quickly and as we saw in the playoffs without Steph they can not generate enough offense. Landing Johnson solves offensive and defensive issues. The pick this year could be used to develop a center or another wing.
Rockets: They do not really need the top ten pick this year considering the loads of young talent all over this roster. Martin gives the rockets a reliable cheap wing who can shoot the ball which was what they were missing in the playoffs.
