Unstructured data is anything that is in written form, natural language, or images, videos and those kinds of things.
If you look at unstructured data, historically they haven’t been used to manage player performance or used to support the decision making of the team. The majority of the analysis has traditionally been focused on structured data, purely numbers that can be modeled and graphed and be compared against each other.
The challenge is trying to find ways of bringing in the unstructured data, so it can be used by the front office, as part of player evaluation, because you have an awful lot less to work with if you’re just using the structured data.
