You need like 30 yards in today's NFL. You start at the 30 and you’re pretty much within FG range when you get under 60. It’s 2 plays and every defense out there is playing soft and guarding the sidelines.
If the Lions started their final drive down 32-31, from their own 30, with 35 seconds left and no timeouts, I don’t think many of us would have been reasonably confident in making a stop.
