If you're Dwight or LeBron, you can write your ticket anywhere you want. If you have an opportunity to play with a couple of good friends who happen to be very good at what they do, build a dynasty for a few years, and go clubbing in perfect weather, how could anyone resist.
However, there aren't many LeBron's and Dwight's who can literally play anywhere they want (if the money is offered). Trust me, a promising young HC who isn't an idiot, a good, young nucleus, a GM who appears to know what he's doing, owner's willing to make the requisite commitment, many first round picks over the next few years..........
I think Boston will be attractive to a lot of very good players. The bigger problem for some players, who are unfamiliar with Boston, is getting past the (mostly) outdated stigma often associated with this city.
