The NFL introduced a new rule prior to this season that touchbacks would result in the ball being placed at the 25-yard-line instead of the 20.

This was meant to dissuade kickoff returners from leaving the end zone, since the kick return is one of football’s most dangerous plays.

It has instead resulted in a spate of kicks purposely placed within the 10-yard-line, because, well, football coaches look for every advantage.

The Lions tried to do this to the Packers today. But the Packers were saved by exploiting a little-known — and, frankly, bad — rule.

By laying on the ground with his feet out of bounds, Ty Montgomery forced the official to rule that he had received the kick out of bounds, resulting in a penalty against Detroit. The Packers got the ball on the 40 and would scored a touchdown on the drive.
