In daily fantasy baseball, there is an everlasting debate about whether BvP data is relevant, or more importantly, predictive. If you don’t know, BvP means batter versus pitcher, and it’s just a stat that tells you how a specific batter has performed against a specific pitcher.

Some analysts argue that just splits are important –- how a batter has hit against lefties versus righties. Others will argue that you can go even deeper and look at single-pitcher splits.

I’ve always thought it interesting that we rely so much on DvP in basketball –- defense versus position, or how well a team defends that specific position –- but not individual matchups, like some in baseball use BvP. For example, the Orlando Magic have given up the third-most fantasy points to opposing point guards this year. But their point guard, DRPM, ahead of guys like tweet me and we can try to become better NBA DFS players together.

You can see the difference between teammates –- look at nbasavant.com has this information via play-by-play data. However, it's not sortable by defender on the site, so you'll have to manually go through and search and organize by defender. Hence my wish to make a database!
