One player's season, told in order: game by game, against his position, where he does his damage, and who he plays like.

Joey O'Brien, Notre Dame S: the 2026 season story

Joey O'Brien is a freshman defensive back for Notre Dame (FBS Independents). He ranks 1377th of 1,841 defensive backs in Division I by the Player Index, which judges every defensive back on the measures that matter at the position, adjusted for the opponents he faced.

01

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. Joey O'Brien's strongest measure is yards per catch on his record at 9.0, 199th of 921 (the average is 11.6). His weakest is interceptions per game at 0.00, 397th of 921 (the average is 0.08).

02

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, 1.8, ranks 886th among 921 ranked defensive backs.

03

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 4th percentile for volume, 50th for efficiency and 15th for impact.

04

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 7 games, Joey O'Brien's best came in week 7 at BYU and his quietest in week 3 against Michigan State.

05

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.

06

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. Joey O'Brien is 758th of 921 FBS defensive backs and 12th of 13 in FBS Independents. Next up nationally is DaShawn Stone of Duke, 0.00 ahead on the index.

07

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 Bryce Djossou of Morgan State.

About this page

A season, told as a story

Every player page tells one player's season in order. It shows where he ranks at his position in the Player Index, what he has done game by game, and how each game measured up against the defense or offense he faced.

What each part shows

The story covers his production against every qualified player at his position, where on the field he does his damage, how his usage has changed over the season, his best and quietest games, and the players whose seasons look most like his. Transfers show the school he came from. Any chart can be switched from the whole season to a single game.

Where the numbers come from

Everything is built from public play-by-play data for this season, with every game adjusted for the strength of the opponent. Past seasons back to 2015 are available from the season menu, so a player's career can be read year by year.
