Right now, Shaq, Big Z, Parker, and Jamison are all 33 years old or older. If the Cavs flame out in the playoffs despite being the heavy favorite for the second year in a row, does Lebron look at this roster and decide that it's not going to be championship caliber in two years?
I think he might. If Lebron is going to be on a team full of role players, wouldn't he be better off in a city like New York, where there are some nice young pieces, and where his exposure would be even greater than it is now? What would the incentive be to remain in Cleveland, if he was convinced that this year was his best shot?
I think this would help extend the Celts window, because whatever outside team Lebron signs with will probably take some time to gel before it's an immediate title favorite. That being the case, our key rivals in the East might be Miami and Atlanta, with Cleveland falling into the lottery.
Also, of course, a win over Cleveland shows free agents that we're still very much in the title picture, making the Celtics situation more attractive.
I want to see the Celts beat the Cavs simply because I want a title this year, but I also think a series victory could play dividends next season and beyond.
