Stevens doesn't seem like the type of a guy that would resign and say adios. Perhaps he's giving Ainge and the Celtics organization an opportunity to find a new coach. Not necessarily an interim coach, but one that would be a coach they would hire for the long-term. It would be a win, win situation. All that would change if the news was broke by multiple mainstream sources that Stevens was leaving. Until then, it just seems like a reasonable and responsible gesture by Brad.
