I designed Pupstatus to help shed light on the actual impact any given player would have on their respective team, offense or defense, should they miss a game do to unforseen events. When I would hear news like "Creed Humphrey is out for two weeks with a calf strain" I had no idea what that might actually do the team. Using this tool you can estimate the actual impact a player has at their respective position and what kind of dent it will put in the game plan of their team.
Using my rosters and statistical data I can assign a numerical value to the physical impact a player has on their team. (Thank you pro-football-reference for the "av" statistc). I visualize this data by creating the lineup and a pie chart determing HOW MUCH imact a particular player might have on the overal value at that position. If the overal value at a position is high and there is a big chunk of red pie, that means the value at that position has been impacted significantly
I aggregate data from several sites. Namely espn.com for injury data, footballguys.com for rosters and lineups and pro-football-reference.com for player statistics.
I've been developing this concept for several years. This is the 2nd iteration of the actual site.
