As for the Poll, I could see him going to the Knicks.
Lebron is an attention whoare of the highest degree, and he's gong to want to be somehwere where the lights shine bright and the entire worlds spotlight is on him.
I can envision him wanting to come to Boston, but Ainge having no interesting in mortgaging the future to make it happen. I can see him trying to join the Spurs, but Popovich wanting nothing to do with a self-obsessed narcissistic diva. I very much doubt the Cavs have any hope of challenging the Warriors this year, so I feel about 70% - 80% confident he isn't staying in Cleveland. I don't think Milwaukee would want him taking attention off Giannis.
Knicks make sense - with Kanter, Porzingis, Hardaway Jr the Knicks have a reasonably talented young team and are proving to be pretty competitive this year. They could use a star on the perimeter and could also use a dominant ball handler, so Lebron would actually be a very good fit there. Knicks fans would love him because he'd immediatley bring wins, and I think he'd instantly make the Knicks a contender again - which is something they have been dying to have for years (decades?). Seems like a match made in heaven. New York also seems like the perfect atmosphere to harbor Lebron's diva attitude, since they've had more than their share of diva's there int he past 10 years.
The Lakers somewhat fit too, but Lonzo ball looks like a disaster, Ingram still doesn't look like a top 3 pick, Randle is a bum, and can't imagine how Lebron's selfish diva (there goe's that word again!!!) attitude would mesh with Magic Johnson...given that Lebron seems to want pull rank and pull the strings on every team he plays on, while I somehow don't see Magic Johnson (one of the few men in the league who has just as much credibility as Lebron) being especially happy to give up his control. Plus going to the west means having to compete with the Warriors and Rockets, and we all know the Lakers with Lebron are not beating either of those teams.
So, I'm going to say the Knicks. The roster fits, since they could use a player with his skill set.
Their phase fits, as they are a young upcoming team that could take a really huge leap forward with the addition of an elite veteran leader. They don't have much in the way of coaching or leadership, so they'd likely be happy for Lebron to come in and tell them what to do. On top of all that it's a city built around bright lights and drama - something that Lebron seems to not be able to get enough of. And it's a city that has been desperate for a winning team since Patrick Ewing left, so they would likely worship Lebron if he can make them relevant again - and we all know Lebron's ego loves nothing more then some worshiping.
