Nobody knows what position Jabari is, and Lebron can literally play every position on the floor at an elite level. Lebron can also literally play and excel with any basketball player worth a god damn, and it seems his motive for choosing his teams is the talent he plays with. Lebron is (or at least was) more similar in role to Dwyane Wade, he chose to play with him, and it hasn't turned out to be burning wreckage.
I also don't think that Lebron fits well with a pure center since that ****s with his getting to the rim and there's a reason the Heat have done things the way they have (tried to retrofit SFs to PF in the hope of getting Lebron more space inside, having Bosh shoot more jumpers and from longer distances with time, and play Bosh at center), and nobody thinks Embiid is going to be close to his upside anytime soon. Similarly with Wiggins, he's not exactly a lights-out gunner either and he's further from his ceiling than Parker.
I don't know about you, but I think Lebron and Carmello (a guy that shares a similar skillset to Parker with [with Parker probably being the better shooter {and worse defender} when all is said and done]) on the same team is a more complementary and interesting dynamic than anything Lebron has had with the Heat. You could make the case that Parker is THE guy over the other two.
