Which metric is commonly featured in live sports broadcasts as an advanced stat?

• A. Expected goals
• B. Win probability
• C. Pace
• D. Defensive metrics

Answer: (A)

Expected goals is the stat you’re most likely to see on the broadcast as the go-to advanced metric. It measures the quality of scoring chances rather than just counting goals or shots, turning what happens in front of the goal into a probability. Each shot is assigned a likelihood of becoming a goal based on factors like how far and at what angle the shot was taken, whether it was a header, the situation it came from, and the context of similar past attempts. As the game unfolds, xG adds up for each team, giving viewers a sense of how dangerous the teams have been and why the scoreline might not tell the full story—for example, a team can create high-quality chances and still be behind, or convert few chances into goals despite high xG.

Other metrics aren’t as routinely shown in real time. Win probability can appear in some broadcasts, but not as consistently across sports. Pace and broad defensive metrics exist, but they don’t translate into the immediate, intuitive narrative about scoring chances that xG provides for live viewing.
