CHICAGO -- Summer means vacation for NBA players who don't make the Finals, and the Chicago Bulls hope their players use this free time to recharge for what hopes to be a healthy regular season. From Derrick Rose's much-debated knee rehab to Kirk Hinrich's never-ending injuries to Luol Deng's season-ending illness, the Bulls season recap needed American Medical Association approval. The Bulls have put together great regular seasons under coach Tom Thibodeau, but haven't been able to field healthy lineups in the postseason the last two years. With no money for new players, the Bulls need the expensive ones they have to be healthy. Something has to change.
