Illegal Blocking

The free blocking zone is a box 3yards by 4yards. Which in most formations covers the center, guards and tackles. Thus the OL/DL restriction they are talking about. With the restrictins of being on the line at the snap and in the box while the free blocking zone still exists, by rule and formation no back or wide out can block below the waist.

thank you some much. What about a TE? I had a coach saying, "if my guys line-up real tight and the TE is really close to the tackle, then he is in the box too."
