Scouting report
Why it matters. Knowing the one or two things a player does best, and where he is ordinary, says more than any single total. Seth Johnson's strongest measure is passes defended per game at 0.50, 177th of 921 (the average is 0.31). His weakest is interceptions per game at 0.00, 397th of 921 (the average is 0.08).
Season production
Why it matters. Totals reward staying healthy and getting the ball; per-game numbers show how much he really carries each week. His tackles per game, 3.4, ranks 476th among 921 ranked defensive backs.
Against every defensive back
Why it matters. Splitting the measures into how much, how well and how many big plays shows what kind of defensive back he is. Among ranked defensive backs he sits, on average, in the 48th percentile for volume, 38th for efficiency and 41st for impact.
The season, game by game
Why it matters. A season average can hide a player who is great one week and absent the next; game by game shows how dependable he is. Over 9 games, Seth Johnson's best came in week 5 against West Virginia and his quietest in week 2 at Iowa.
Where he does his damage
Why it matters. Where and how a player makes his plays shows how his team uses him and what a defense has to take away.
National and conference
Why it matters. A national rank shows how a player stacks up beyond his own league, where the competition can be very different. Seth Johnson is 450th of 921 FBS defensive backs and 55th of 103 in the Big 12. Next up nationally is Adon Shuler of Notre Dame, 0.00 ahead on the index.
Defensive backs like him
Why it matters. Comparing a player with his closest statistical matches puts his season in context beyond the rankings. His closest match this season is Felix Matos of Long Island University.
