"At one workout in March 2008, when Yoder Begley said she was mourning the recent death of her dog, Salazar told her she was bringing down the rest of the team. The next month, Yoder Begley said Salazar told her that her laugh was annoying him and other runners. Then, she said, he asked her to sign a contract stating that she would not befriend other athletes on the team. Other Oregon project athletes were not asked to sign the contract, as she was led to believe they would."
Matthew Futterman has more on Begley, who details being ridiculed for her weight during her time with the NOP.
