To be honest all of their S5 apart from LeBron is trash. Its a very tricky situation, because
a) Boston can offer a better trade during the offseason, so unless the Lakers offer something great NOLA has no need to trade Davis now.
b) LA cant wait until 2020 (when Davis becomes UFA) because LeBrons time is running out.
Unless Klay and/or Durant leave GSW i cant see anybody beating the Warriors in the next couple of years anyway, so they probably have to hope that Durant goes to the Knicks and/or that GSW doesnt offer Klay the max contract and that he will then join the Lakers.
Davis+LeBron+a couple of role players wont be enough to beat GSW, they need someone like Klay, Kawhi or Kyrie, but i dont know if they have room for 2 max contracts ...
