A Comparison of 2018 NFL Draft Grades

Let's imagine for a moment that you're an Arizona Cardinals fan, and ESPN's Mel Kiper Jr. is your go-to source for NFL information. You were probably a bit frustrated when he gave your team a C+ for their overall 2018 draft grade. You call your neighbor to tell him the bad news, but he tells

Let’s imagine for a moment that you’re an Arizona Cardinals fan, and ESPN’s Mel Kiper Jr. is your go-to source for NFL information. You were probably a bit frustrated when he gave your team a C+ for their overall 2018 draft grade. You call your neighbor to tell him the bad news, but he tells you that Gennaro Filice of NFL.com gave the Cardinals an A. You hang up the phone, pondering the question: “How can two experts assign such different grades?”

This is just one example of how a reader’s perception of their team can be skewed by the sites they favor. The goal of this data visualization is to compare draft grades from five notable websites (ESPN, Yahoo, Sports Illustrated, CBS, and NFL.com) and see just how much their results can vary based on the same information.

Some teams, like the Chargers, stayed consistent across all the sites. Others, like the Saints, proved pretty divisive.
Use the dropdown lists to compare different media outlets. The darker the circle, the greater the grade difference. Play around with the data and see what interesting conclusions you can draw about your favorite team, or your favorite analyst.
