More Visualization: Defensive UFRs
For each player, Brian assigns a plus/minus total, and thus, an opportunity for a simple visualization of each player's performance over the course of the year. Ignored for now: the pressure/coverage/tackling metrics. Just player performance, pure and simple.
So, you think this calls for a ... hmm ... graph?
Graph:
A little explanation. Each game's defensive per-player ratings are shown. For a particular game (say, "Eastern"), each player's plus/minus is shown as a simple bar graph. Blue (to the right) shows a player's positive rating for the game, and Yellow (to the left) shows their negative rating. A single red dot shows the "net" rating for a player for a particular game (i.e., plus - minus); you want these to be right of the center axis! Per Brian's charts (Western, Notre Dame, Eastern, Indiana, MSU, Iowa), the players are grouped into three sets: Defensive Line, Linebackers, and Defensive Backs. Finally, within each grouping, players are ordered by the total number of positive plays they have made on the year (somewhat arbitrarily).
I'm not going to do much/any analysis of the data, but some obvious things do stand out. First (no surprise), Graham is a beast. That MSU performance is ridiculous! Second, the D-Line is a strength of the D and seemingly getting better, which bodes well. Third, linebacker play: ouch. But nice to see Ezeh with a net positive (red dot to the right) in the Iowa game; Stevie Brown has also done reasonably. Finally, D-backs: also some ouch, particularly against ND and Indiana (Cissoko unfortunately a big part of that). Now if we could just get Williams to shore up a bit...
Anyhow, that's it. Not too fancy, but I think a nice way to look at Brian's overall player grading. Now I'm sure you want to give some ... feedback?
