About

Tyler NFL is a one person analytics site. The centerpiece is a 4th down model that grades go or kick decisions by win probability; around it are stat leaders, a daily history note, and the occasional article about what the numbers say.

Data comes from the nflverse project. The models are built and maintained by Tyler; the site reports what they say and keeps a running record of graded calls: each time a coach's choice gave up win probability, by how much.
