yes! Veronica Burton v. Courtney Williams last night, but that's the only one.

Kelsey Mitchell v. Rachel Banham and Arike Ogunbowale v. Brittney Sykes (both last night) are the only two non-finals games where a player has had 1 possession total.

Did Veronica Burton beat Courtney Williams that bad?

Burton's win was the fastest Unrivaled 1-on-1 tournament victory for any non-finals game.

some definitions for the stats:

true shot: any FG attempt + free throws stemming from shooting fouls. it's a middle ground between eFG% and TS%

usage percentage: (true shots + turnovers)/(player's offensive possessions). how often a player was used when on the floor.

Scatter plot showing usage percentage on the x-axis and points per true shot on the y-axis. True shots are defined as a field goal attempt or a free throw attempt resulting from a shooting foul. Usage is calculated as a player's true shots plus turnovers, divided by their number of offensive possessions. Chelsea Gray and Paige Bueckers are the highest efficiency players as of February 3rd.

Who are the highest usage and most efficient players in Unrivaled?

Paige Bueckers is coming close to taking Chelsea Gray's efficiency crown.

ICYMI: Assessing which team has the best three-player lineup in Unrivaled should be an easy task. The league doesn't publish lineup stats, though, so I went ahead and pulled the data.

important caveats:
- small sample size (2024 alone, many players only have 3-4 reps. 10 seconds, or as few as ~2 seconds for stall/bull score, isn't enough for a comprehensive evaluation and is subject to noise.)
- no film (makes ground truth validation for contact onset tough)

Here are the top six reps by stall score. I found these handy for assessing whether the metrics were measuring what they were intended to measure!

Secondary metrics:

Stall Score (did you stop the rusher’s progress?) and Bull Score (given engagement, did you drive the blocker back?). Both focus on what happens after contact onset.

Top 3 leaderboard for both, along with media quotes from 2024 East-West Shrine Bowl Practice:

Primary metric: DL Depth Allowed at Frame 25

Median time to throw was ~2.68 seconds in 2025; ESPN Analytics pass rush win rate is anchored at 2.5 seconds. Use DL depth @ frame 25 as a proxy for how much ground an OL gave

Top 5 leaderboard below, small sample size caveats apply:

spaghetti plot showing the mean, median, 10%ile and 90%ile curves for closing velocity relative to the identified contact-onset frame. closing velocity collapses near the contact-onset frame.

Feature engineering and "contact onset":

1-on-1 reps have phases (get off, set, engagement, etc.) and properly quantifying a lineman’s performance can be tricky.

So, approximate frame when closing ends and engagement (likely) begins. It's not ground truth, but it's a start.
