Possible Meanings, off the top of my head:
1) Lebron just wants to see Eddy turn his life around cause his mutual agent and friend have spoke to him about
2) Lebron wants to talk to somebody that has played in both NY and Chicago (in that sense, he should talk to Crawford, JYD and Starks, to name a few)
3) Lebron knows that if he comes to NY, the Knicks are better if Curry has some value at all (whether to trade or play)
4) Lebron likes to talk to people who have had more disappointing playoff experiencing (as is Eddy was left out)
Honestly, I think Lebron is doing his due diligence, but there must be some leaning toward NY. You can talk to a guy without having to work out with him (and clearly Eddy is not known as a workout warrior). So, working out with Eddy is either charity or personal interest. I could go either way on that one...
