I don't like it either. Guys spent more time doing that instead of reading the alignments and getting ready. So many times i felt like they were late off the ball and unprepared b/c they were just getting set as the ball was snapped. I think they need to stop that as well. We don't need a strong side DLine. You can adjust to the strong side by sliding the Dline over, tilting, slanting, bumping out a DE or rolling the LBs over. There's no need to flop the whole line. NOBODY in the NFL does it.
