What happened: Matthew Stafford threw a pick-six, then drove for a go-ahead touchdown in the fourth quarter. The two drives came back-to-back to flip the lead late.

Why it matters: Answering a turnover with a lead-taking score limited the damage from the pick-six. A fourth-quarter lead change puts late-game leverage on the other sideline.

What to watch: Watch whether the late lead holds through the closing minutes.
