the Lakers with AD/Harden probably beat the small ball Rockets with Lebron and Westbrook
Lebron and the Bucks manage to beat the Heat relatively easily
Lebron and the Mavericks probably struggle against the Clippers and Nuggets, but I think they get it done, especially if KP stays healthy.
Lebron and the Clippers with PG definitely make it to the WCF, but running into AD + Kawhi would probably result in a Lakers win in the WCF. Lebron would still be playing as of today though.
