The OL Radar Chart

What is a radar chart?

A radar chart is a way to quickly and effectively present information, especially when showing how a player compares across multiple statistics and their percentiles in those statistics. It has become one of the default ways of showing player stats in the other football (soccer) for how easily it conveys data, and was popularized by Ted Knutson and the team at Statsbomb.

Why use them?

Radar charts give a quick and easy look at the kind of player you are looking for. The statistics represent different OL archetypes. Do you have a pass set specialist, a road grater in the run game, or an all-rounder?

However, there are a few things to remember when looking at these charts. All this represents is statistical output, and if you had players on other teams or in different situations, it would most likely affect all the numbers.

This is only a tool to help evaluate players and add extra context to a holistic evaluation.

The Stats and the Data Set

The data is all sourced from PFF and includes all OLs who played FBS football from 2015 to the present with at least 150 snaps, and compares the OT or IOL against their draft year and position pool, unless otherwise specified. These stats were chosen because I believe they best exemplify what type of OL a prospect is.

1. PFF Offense Grade – A proprietary PFF rating capturing an offensive tackle's overall contribution.
2. Pass Block Grade – A proprietary PFF rating evaluating a tackle's effectiveness in pass protection.
3. Pass Block Efficiency (PBE) – A composite metric that weights sacks and hits allowed more heavily than hurries, measuring how cleanly a tackle protects relative to their number of pass blocking snaps.
4. Pressures Allowed – The total number of quarterback pressures (sacks, hits, and hurries) a tackle gave up. Lower is better.
5. Sacks Allowed – The total number of sacks surrendered. Lower is better.
6. Run Block Grade – A proprietary PFF rating measuring overall run blocking effectiveness across all scheme types.
7. Gap Scheme Grade – A proprietary PFF rating evaluating a tackle's effectiveness in gap and power running schemes.
8. Zone Scheme Grade – A proprietary PFF rating evaluating a tackle's effectiveness in zone running schemes.

Now lets look at some fun charts!
