BOS sends: Bradley
OKC sends: Adams, Lamb, Novak
For us the trade is twofold - we get a real defensive center and gamble on Lamb. If Lamb breaks out, then we get a decently sized shooting guard. Novak is a cost of making a deal - need to make salaries work and provide additional incentive for OKC.
For OKC, they finally get they missing defensive spot up shooter to pair with Durant and Westbrook. Bradley is also cost-controlled, and is on a very cheap contract. In addition, they get rid of Novak (does not play) and Lamb (barely ever plays) thus freeing up both roster spots and playing time. More importantly, for Thunder this trade saves on luxury tax which they get into after extending Kanter. They do not really have a use for him anymore with Kanter there, and a lot of cost-controlled back up bigs such as McGary and Collison.
