User blog comment:Epic~00/Why Total Drama All Stars Was Such An Abysmal Season (PART 1)/@comment-24466939-20140825204910/@comment-24152851-20140826050845

Sam replaced Brick (who was originally planned), because he had more "drama causing potential".

And Jayden's right. He didn't cause Cam's elimination. He tried to eliminate Cam, but failed several times. Then Ezekiel beat him to it. He had more of a role in eliminating Scott then he did Cam, and even that wasn't direct.
