Stating that Miami and New York have better odds of signing Durant is completely fallacious conjecture. The Celtics have a much brighter future than both of those teams, with the tools for sustained success for the foreseeable future. Boston is trending upward, Miami and New York are fading or stuck in obscurity. I think that OKC has the best chance of signing Durant because of the moves they have made this summer and it's easier for KD to stick around and make more money there.
Having said that, the Western conference is contentious and the path to a championship is a lot tougher than in the East. The appeal of Boston is that we are on the brink and Durant could realistically win several championships here, given that he has the right pieces around him. Boston is going all out to make this an appealing destination for free agents, considering the coach that we have and the fact that they are planning enhancements like the state of the art practice facility.
Why would KD meet with other teams? He and his agent are doing their due diligence and it would be poor business to not hear what other teams have to offer. It's like the decision between settling at your current job or exploring other opportunities that may be more fruitful for one's career. So don't get your hopes up, but there's also no reason to despair and doubt the efforts and potential of the Celtics. Ainge's acumen led us to having a top 3 pick in this year's draft, and most likely the next 2 drafts as well, so we should be grateful and temper our expectations.
