Jerry Angelo called an impromptu teleconference with beat reporters late Sunday afternoon to refute an online report about left tackle Chris Williams' back injury that Angelo thought cast him as a liar. "Nobody was trying to pull the wool over anybody's eyes," Angelo said testily. "Nobody is covering their ass." Williams disclosed after Sunday's practice that he had a herniated disc when the Bears drafted him, an injury suffered three years ago at Vanderbilt. "Nobody is twisting the truth or embellishing it," Angelo said. "I could give a [bleep]. I could give a [bleep]. If we screwed up, I would tell you, 'We screwed up.' Hey, if we said this was 50-50 and we just rolled the dice, I would tell you that."
