Yup. Dude in the video is right on the money. DeMarcus Cousins to the Celtics would be good not only for Boston but for the entire NBA. Right now Cleveland and Golden State are the only legitimate contenders. That's just not interesting. The NBA need another top tier team to challenge those two. Cousins getting traded to Boston would absolutely make them contenders, especially considering the front court advantage they would have over both those teams.
2017 BKN pick, Jaylen Brown, Marcus Smart, Kelly Olynyk, Amir Johnson for DeMarcus Cousins & Omri Casspi is a trade that benefits both sides and should have been made by now.
Tough nuts if Stevens doesn't want to coach Cousins.
