This website is designed to act as a central hub for all of my apps and other creations. My content can generally be found on twitter (@JosephJefe). I also write articles and produce graphics for KC Sports Network. You can find a list of all my articles for KCSN here on Substack.

Shiny Apps

Each of the Shiny Apps listed below has a full page guide on this website that you can access from the left hand sidebar. This is simply a listing of them along with a short description.

Game Preview Cards App

The Game Preview Cards App allows you to choose a game from the current week (or previous weeks) and generate a preview of those two teams side by side. It generates a list of different stats and rankings for both teams.

Trade Calculator App

The Trade Calculator App allows you to input the draft picks in a trade, and it generates a table of 6 different trade charts, and how much value was gained or lost per each chart.

Team Builder App

The Team Builder App allows you to input players from free agency and the draft, and create a 53 Man Roster or a Depth Chart view of those players. This is especially useful for March-April during free agency and the draft, and then again in August when people are predicting the 53 Man Rosters.

Team Schedules App

The Team Schedules App allows you to select a team and a year, and it generates a team schedule with the team colors. It is designed to be a background or wallpaper for a smartphone.

Shiny Apps: Historical

These apps are useful for historical purposes only. In Week 15 of the 2023 season, the NFL removed access to their Participation Data. These apps relied on that data for their output, so they are no longer useful for current games, but I haven’t had the heart to delete them yet. They still work properly for all games up to Week 15, 2023.

Team Formations Shiny App

The Team Formations Shiny App generates a table of a teams formations for a single game or a range of games. It also lists every player and how many snaps they got in each formation.

Pillbox Charts Shiny App

The Pillbox Charts Shiny App generates a graphic with a list of all the players who played in a game, along with a tick, or pill, for every snap they played. These graphics also show the down, the player with the carry/target, whether it was a pass or run play, and the drive outcome.

All-22 App

The All-22 App is a table of every snap in a specific game or range of games. It is designed to assist people who watch film to find specific plays. This app provides the quarter, time, down and distance, as well as many other data items that help to identify specific plays a person might want to watch.
