Bruce Ratner is orchestrating a big demonstration today in support of his increasingly doomed-looking Atlantic Yards project! So which celebs did he enlist to headline the rally and win over skeptics? Former Nets Darryl Dawkins and Alan King, neither of whom has played basketball professionally since the 1980s. A-list! He also managed to persuade shrinking violets Al Sharpton and Curtis Sliwa to overcome their aversion to attention and speak at the rally.
