I've noticed that one of the defensive tackles - seems to be NT, as he's just outside the center - will sometimes line up with his body angled. I saw this last year for the the first time, and never see it in pro games, and was wondering if anyone knows why they do it. I figure they're probably setting up a stunt. In the game yesterday he would sometimes line up straight, sometimes angled, and when angled would sometimes go straight in and sometimes go at an angle into the center. Thanks in advance.
