The Lakers are too guard-heavy and need more wing 3 and D role players that can work behind LeBron and AD, especially after the revelation of Westbrook's 6man performances, they desperately need a shooter that can defend and that can play more minutes. The Thunder are rebuilding but can take Kendrick Nunn's contract since it is expiring and both players don't really serve a massive purpose on the thunder, so taking on Nunn's contract doesn't hurt or benefit them. This being said, having someone that can play behind Shai, is always a good thing, especially because the Thunder are too wing heavy as well
