One, OB1 got lucky. Maul could have killed him. He just had some back luck. Two, Dooku has about 50 years of experience over Maul, and it's silly to think that Sidious would pick a weaker apprentice. Also, OB1 is about 35 now, so he isn't a youth anymore. Dooku will rely on experience to defeat the weak OB1 and Anakin. Hahaha!!!!😈
