Sure, Celtics fans are thirsting for some "fireworks" this summer. Prepare to hear plenty of rumors about Demarcus Cousins, Jimmy Butler, and a the pursuit of a certain free agent out of OKC. Danny Ainge has been stockpiling assets for years with the hope it all adds up to hooking a big fish that leads the Celtics back into title contention. There's no doubt that the Celtics are improving, Brad Stevens has gone from 25 wins > 40 wins and a playoff appearance > 48 wins and two playoff victories. While this year's result may have been a little shy of what fans wanted to see, it was in line with expectation and the rebuild is still very much on course.
