The Chicago Bulls have a problem. Their Derrick Rose has wilted. And until he springs back to life, the NBA’s best team could be in trouble. DANCE OFFS you think you can dance? Dont. Leave it to these professionals.Bothered again by a nagging back injury, Derrick Rose sat out his second straight game Sunday afternoon in Boston, giving Celtics point guard Rajon Rondo the perfect opportunity to shine. And did Rondo ever take advantage of Rose’s absence.The sixth-year guard abused Chicago backups C.J. Watson and John Lucas III, tied a career high with 32 points and added 10 rebounds and 15 assists — the ninth triple-double of his career — as he led the Celtics to a 95-91 win over the Eastern Conference-leading Bulls.
