Chicago Bears owner George McCaskey was accountable for the mistake of signing trouble-prone defensive end Ray McDonald. McDonald was arrested for domestic violence over the weekend and released by the team. He allegedly struck a woman who was holding a baby. McCaskey said it was "my decision, ultimately, alone." to sign McDonald. He didn't blame general manager Ryan Pace for the ill-fated personnel decision. “Not at all," McCaskey told reporters. "We have complete confidence in Ryan." McCaskey said he didn't have involvement in cutting McDonald on Monday. “I wasn’t involved because I didn’t need to be,” McCaskey said. “They knew what needed to be done and did it.” Why not talk to McDonald's many accusers of domestic violence prior to signing the guy? "One of my concerns was the bias anybody has in that situation," McCaskey said. McCaskey just consulted with McDonald's parents curiously.
