Going to the lakers would be a dumb move, even if paul george was to join him. They still won't beat the warriors, that might be a sweep or 5 at best.
They will most likely go 6 or 7 with the spurs and that's no guarantee that you'll beat them.
Bron in the east atleast guarantees you a trip to the finals for atleast 2 more yrs, boston and sixers are not ready to compete yet.
Cavs best bet would be getting PG for love or atleast melo if he takes the buyout. But PG on the cavs instead of love you're going atleast 6 or 7 games against the warriors. You can put PG on durant and lebron on draymond and this way lebron can concentrate more on running the offense.
I definitely think a team of love, melo, lebron and kyrie are good enough to take the warriors to 7. Obviously you gotta convince melo or love to take the 6th man role to start TT and then you can close the 4th out with love, melo, lebron, smith and kyrie
