No I'm not from Cleveland, but used to be a Cavs fan when I was a kid (I did live in Ohio for a couple years when I was young). When I visited friends who happen to live in Cleveland during the LeBron years and we went to playoff games together, I became one again. I cheered for the Cavs because of LeBron.
I would try to respond to all your points but there's been much chatter since. I will bring up points and ask questions regarding the above statement though:
1.) You state here you were a Cavs fan - past tense - which means you either became a fan of another team or gave up following the game for a period or altogether Why is it not ok for Lebron to play for another team but it's ok for you to either root for another team or drop the Cavs as favorite team? This organization you admit did a poor job of building a team around Lebron - so why is he supposed to be a Cav for his entire career after 7 years of falling short? If you had a conversaton with Lebron I think he could throw that one your way and what would you say? This undying loyalty a player should have to an organization would just not benefit most players (maybe if you play for the Spurs). Look at what happened to Pierce and KG. They brought a ring to Boston, Pierce was a Celtic his entire career and they got traded so Boston could rebuild. Where's their loyalty? KG showed loyalty to Boston verbally and through his actions by spurning the Clippers - and what did he get for it? IF you really feel how you do you should be burning up about this trade too because this stuff works both ways. It's just not wise to be unquestionably loyal to something that probably wouldn't be to you. The NBA is a business and that's what every organization says when they trade their players away - in a game that will remember you for what you've done, Lebron more than made the right move.
2.) Just remembering some of the other things you said: Jordan had no reason whatsoever to leave Chicago. Did Jordan improve the atmosphere and make guys want to come play with him? I don't think so I think the Bulls organization had more to do with that - Michael Jordan is probably the most arrogant player in the history of the NBA as great as he was. The Bulls built around him and the guys that played with him didn't necessarily like him but they wanted hardware - if you know of any players, please name some guys Michael personally brought to Chicago.
