Master Mundi seems to be the third most powerful member of the Council. Aside from Mace and Yoda, Ki-Adi-Mundi is the only one with a speaking role amongst the Jedi Council. He's also the only Jedi we see fight off Order 66, aside from Yoda. Ki-Adi senses the betrayal and defends himself, killing several clone before being overwhelmed. If Mace had brought Ki-Adi-Mundi instead of one of the lame members of the posse, could he have prevailed against Palpatine? Side note: What if Yoda had joined Mace before they moved to arrest Palpatine? Would that have made a difference?
