—When Matt Patricia launched his challenge flag onto the field from atop his coaching perch behind the Detroit Lions bench last Thursday, he did so more out of curiosity than with any hard and fast expectation there was a penalty on the play.
Patricia and many of his NFL coaching brethren are trying to understand how officials will mediate new rules that allow pass interference penalties, both called and not, to be reviewed, and the thought is the preseason is as good a time as any to find out.
