Generally speaking, stats are public domain as they are a public event that occurred. Because a sports league may disagree with this position doesn't mean that it isn't true. However, its entirely possible to violate a given site's TOU by scraping the data, it doesn't mean the data itself isn't allowed to be compiled or distributed.
