Let me try and explain the difference between 1/4" gap and 8" opening. We all know that no matter how hard we try, bolt heads, welds, rivets and staples will prevent the bumper from full contact with the frame. After a few years of discussion, First realized that the movement of a bumper in a full hit with a 1/4" gap behind it, is not going to compromise the bumper structure. However, a opening in the frame of greater than 8" in width and more than 1/4" behind the bumper will actually result in cracking of the 3/4" plywood or total failure of the bumper. We want you to play as much as is possible. If your bumper fails and parts of your robot get damaged or start dragging around the field, your chances of fulfilling the "play as much as possible" go down the drain.
