Following his Celtics' (still sounds weird) elimination at the hands of the Miami Heat, Shaquille O'Neal finally called it a career after 19 seasons and four NBA titles. The MDE couldn't get that one last championship (and couldn't stay healthy this last season), but with a possible extended vacation and some much-needed rest, who knows how he'll feel when next season gets around to starting? If MJ taught us anything it's that no retirement is etched in stone. Not sure whether we've seen the last of the Diesel (hey, at least we can hope, right?)
