I'm not sure the data in question here would qualify as "facts" like a batting average or win percentage would. These are researched estimates. Different outlets would come up with different numbers depending on the researchers and techniques they employ. Ergo it requires a degree of skill and creativity. But as you say, the point is moot. The collection itself should certainly be covered by copyright whether its contents are a mere collection of "facts" or not.
