I doubt AD will reject the contract given to him but there is no point of him not getting traded neither, they can do a sign and trade.
The problem is that Lakers are not willing to send any of their young players right now, it happened when Kawhi was the discussion, they didn't give any of their young players for someone like Kawhi who is a superstar and a MVP candidate, they of course rejected giving any of their young players for Trevor Ariza which kinda makes sense.
If they want to get someone like AD they will have to give some of their young players no matter what, AD won't come for free they need to spend some money for it or at least assets. Hence I think Lakers should start looking at their young core and start considering how much they worth. With Lebron+AD+Kawhi they could easily get the ring without a question.
I dont think that will work or could work.
It is different with the super Miami before because Bosh could always give way and Wade have already experienced having a big man at his side which is Shaq.
But Lebron and Kawhi together with an AD? I doubt they can make some sense to them. It will also defy the balance of NBA which will make it boring only.
I would rather have Lebron + AD or Kawhi + AD rather than put them all in one team.
NBA is not Lakers only. They will be losing money if no one is watching the other teams.
If the deal will workout for this three to play together, west finals would be really much interesting to watch, Curry, Durant, and the boogeyman against Lebron, Kawhi and AD, the game will be against coaches and how chemistry will be blend when super team will play against each other, just like watching NBA all star night..
