Pros and cons to all ideas, but I know that at least one national league is currently using this idea. In fact, all rolling pulls going through the endzone stay on the line where they went out, i.e., not brought to the goal line. They went one step further and moved the pulling line up to a line at the brick mark so that, intentionally, offense would have a worse starting position. The reasons for implementing this were reported to be: 1) Getting a pull to roll through the endzone then out the side was considered a “skill shot” and should be rewarded with a field position advantage. 2) It was considered to be more exciting play to have offense start deeper with less dump options, defense arriving sooner, and more callahan possibilities. 3) They did not believe defense has the advantage; quite the opposite. But to be fair, they play on a slightly wider field which gives offense more swing space. Still, some will argue that games with a fewer defensive play turnover possibilities, isn’t the most interesting.
