Prior to 2020, the ACC was divided into two divisions: Atlantic and Coastal. What was the reasoning behind these divisions? I’m not sure, but it clearly had nothing to do with geography. For example, the Pittsburgh Panthers are in the ACC Coastal, but the Boston College Eagles, Syracuse Orange and Louisville Cardinals are all in the ACC Atlantic. The Florida State Seminoles are in the Atlantic, but their nearest neighbors to the North and South - the Georgia Tech Yellow Jackets and the Miami Hurricanes - are both in the Coastal.
