We all watched the first few games of the year as LSU's defensive line was flagged again and again (and again) for their coordinated shifts before the snap because they were thought to be trying to induce movement on the OL... and now, I watch Arky do it again and again, and instead of them getting flagged for it, our OL is. Can anyone explain to me whatever the nuance is in the rules that makes it illegal for us to both attempt AND fall victim to?
