I have a question. I'm watching the ravens/panthers game, and the lineman for the Ravens are lining up sometimes up to 1 yard behind the center. Even on this last touchdown play. Technically, isn't that an illegal formation? I don't understand why it's ok. Anyone know? I know there has to be 7 on the line, and that the tackles have to be covered, but I know I saw some tackles taking penalties earlier this year for being to far off the line. Was there a rule change?
