This all hinges on whether or not you think that the current Celtics plus Lebron (and maybe a few low-salary vets) would be enough to beat the current Warriors. I think I'd take that tisk, but I can definitely understand why some people wouldn't
I was coming here to say the same thing so TP. Is the rest of our roster better than the Cavs roster without Lebron? I honestly don't know.
GS seems so far ahead of everybody else, including the Cavs, that it isn't just an obvious 'yes'. Would it be easier to win a ring with Lebron on our team against a currently stacked GS team or easier with a Cs team that isn't quite as good, but is going against regular (not transcendent) top end talent? A team of that caliber will likely never be able to be assembled again because of last year's salary jump.
Only one team can win the championship. It would be fun to be actual contenders, but I don't really want to be solidly 2nd for three years in a row and then start over from scratch.
EDIT: I did not answer, but only because I am a totally indecisive person.
