McMichael was brought out to meet the media after it was made clear to everyone that McMichael would answer one -- and only one -- question relating to his off-the-field issues.
So the first question to McMichael was: "Could you comment on your arrest and possible suspension?" His reply: "No."
After several football-related questions, McMichael was asked whether he had a problem with alcohol and told the reporter, "Do you?"
After the reporter answered, "I don't," McMichael just said, "OK then."
The reporter then asked McMichael whether he had a problem with his anger, and McMichael replied, "Anything else?" He then got up from his chair and walked away.
McMichael was arrested in Georgia on July 9 after witnesses told police that he had given his wife, Cawanna, a bloody nose. It was the second time in 13 months McMichael had been arrested for allegedly hitting his wife.
Coach Nick Saban talked about McMichael earlier this week.
"Regardless of whatever the consequences of this circumstance, maybe we can help him from having significant problems in the future," Saban said. "We want to help him in every way we can. Randy has been a good guy in a lot of ways on the field as a leader and a well-liked player with a lot of spirit as a competitor.
"He is a hard guy not to like and it's unfortunate that a few things have occurred that doesn't enhance his legacy as a person that we both would like for it to be. Hopefully, we can do something to correct that in the future."
McMichael reportedly is facing an August court date. If convicted on the charges, he could face a four-game league suspension.
McMichael did address football issues, saying there was no way the Dolphins would go 4-12 again.
"I expect us to win," he said. "I'm not going to sit there and say we're going to lose. If you ask me, I'll say that we're going to go undefeated and go all the way because that's the way I feel about this football team. We still have a long way to go. Everybody still has to get on the same page as far as the offense, defense and special teams but that's what training camp is for, so guys can jell together, and that's what we're doing right now."
