I wonder how the position is calculated in American football:
- The position that the snapper snaps
- The position in that the holder fixes the ball and the kicker kicks.
For example, in the record breaking 66-yard field goal of Justin Tucker on Week 3 of 2021 season between the Baltimore Ravens and Detroit Lions,
The previous play was stopped at DET 48. When I see the video, the snapper snapped at DET 50 instead of DET 48. Why did they withdrew two yards, and why is the kick 'just' six yards behind the snap, not five or seven lines?
