she had the balls to put up Amanda and McCrae
I've seen this sentiment expressed in a number of places but don't think it was a "ballsy" move at all. She had clear numbers when she nominated the two of them (Judd, Spencer, and Andy were for it, as was Elissa initially). The fact that no one in the house did it up to that point speaks more towards Elissa's personal biases (as it would have made most sense when she was HOH the week prior to put them both up with Aaryn as a replacement nom).
It would have been a "ballsy" move had she put the two of them up without numbers and convinced the houseguests to get one of them out. As it was, she had the power and numbers and made the only sensible nomination. Smart move, sure. But ANY OTHER move would have been ridiculous.
