BZ wouldn`t do a thing against TTJ Obito. Madara admitted that Obito could prevent him from using his trump card by being Jinchuuriki. He even thanked Naruto for weakening Obito in the first place. Preparation of Obito for casting IT also affected him briefly. His statements about being able to cast IT under those circumstances by himself could be an act of self-confidence, cause i see no ways for him to overpower Obito in a row fight.
