Let me know if you need any help. We built a machine learning service called hopdata and I have been looking for a sports API to link into so we could do something similar to fivethirtyeight.

Sounds good. What type of data would you want to get from a sports data api?
At this point, I had it in my mind as a broad and large undertaking, we would really need to dig into what information is available. For instance, if we look at baseball, we could make predictions based on historic outcomes and real-time scores but it would be much better the more granular we can get. Current score, current inning, current outs, current count, which players are in the outfield, who are the next 9 people to bat, who is pitching, which ballpark, the weather...
That makes sense. I feel like the more granular and real time you can get, the better
