He didn't say he was offended by the language. He was offended by being talked to like that. He said, "The style that Haley had coaching. You're not gonna get in my face and 'mother-F' me and think I'm not gonna say nothing. Like I told him, when I was there, and I told Pioli, 'I have kids, and I don't talk to them that way, so you're gonna be speak to me that way.'"
It was a respect issue, not a language issue.
