Yeah, I mean one of the reasons he purchased Coca-Cola was actually because of what Roberto Goizueta did when he came into the company. At the time Coke was #2 in supermarkets behind Pepsi.
Goizueta did a lot of great things. He separated out the bottler business and got them to focus on returns on invested capital with every investment they made. He made a ton of money for shareholders. Buffett has remarked that he held KO stock too long but now I believe he keeps it mainly to collect the dividends, his cost basis is low.
