Lions coach Matt Patricia said he treats every practice like it's being filmed, which is why it's important to focus on fundamentals, not scheme.
Allen Park — The Detroit Lions, like most NFL teams, have a strict policy about what media members can report from open practices. Revealing specific play calls, formations and anything related to strategy is strictly prohibited.
Taking of photos and video also is limited to a brief window early in practice, while photographers are asked to keep their shots tight, again, to prevent any insight on formations.
