I thought he was trying to come up with ways that his client will be seen as separate as the judge determines a directed verdict. ("You see judge, he is painted with the brush that is the McMichael brush and not by his own deeds." kind of thing.) All that he was saying is that his client could get lumped in with the other defendants by the jury. Gough missed his chance to get his client tried separately which would have been the perfect way to make sure the jury looked at his actions and his actions alone. I think he miscalculated the impact of his client "hitting" Mr. Arbery with the truck and penning him toward the murderer. With all of the information that has been testified to (his client's interview with LE included) his client does look guilty. He is throwing everything including the sink into this pot to try and get him out of this soup. I don't think it works. IMHO.
