Absolutely not! In fact, the move has the opposite effect on me and I've lost even more respect for him. I don't understand how anybody could gain respect for him after this.
LeBron left Cleveland, the team that build itself entirely around him, and ran to Miami for an easy way to far track to a title.
Much as we all hate Miami, Pat Riley welcomed LeBron with open arms and gutted the entire team so that he could join forces with Wade and Bosh and win those titles. LeBron or no LeBron, there's no titles without Pat Riley working his butt to the bone to put all the right role players around those guys. He build that team around LeBron, while Wade and Bosh sacrificed their own spotlight to let him be number one and let them win some rings.
Now Miami, in a major upset, gets absolutely embarrassed by the underdog Spurs 4-1, and LeBron suddenly Rasmussen the Heat won't have such an easy path anymore next year...so he jumps ship again back to Cleveland where he has two young Guys with superstar potential.
LeBron is a leech, not much better than Dwight Howard. He goes to a team, ducks everything they have it off them, then when he feels like there is no life left he moves on to the next host. Disgraceful. Then to make matters worse he goes on to legend that is all for sentimental reasons...really? I guarantee you that if Miami won that title 4-1 instead of the other way around, he'd be resigning with Miami.
