Well, I believe LeBron knows exactly what he's going to do. There won't be any truly new data between now and the time he signs and after all this time in the league he knows all the relevant people. I expect him to end up in LA and sincerely hope he doesn't' land in Philly.
I won't read the Ringer piece as I despise Tjarks and don't value his opinion at all.
That's the right choice. Tjarks piece is awful, in significant part because he doesn't understand the salary cap at all. For example, he operates from the premise that salaries need to match when the Celtics actually only need to get to 80% of Lebron's salary. He also, as a smaller issue, is proposing the Chris Paul pick up option and trade move but is using Lebron's salary next season as the target when that trade would happen this season because the whole point is to preserve his Bird rights by trading him not in his final contract year. I can forgive the latter mistake as it is pretty nuanced and new, but the matching issue is pathetic as that rule has existed in relatively similar form for a long time.
The upshot of all this is that his trade packages are wrong. The Hayward deal can be straight up. There is no reason Morris would be involved unless Cleveland wanted him. The Kyrie proposal doesn't need to stripmine the roster. Kyrie, Morris, Yabu, and Nader is enough salary. You can swap in various versions with Theis, Semi, or Rozier replacing some of the latter two and still make it work.
In the end, I don't see Lebron wanting to come to Boston, but if he did, I think a trade based around Kyrie getting shipped out to a third team and Cleveland netting whatever Kyrie returns plus the above filler is a pretty great return for a departing free agent.
