I'm not sure if this concept has come up for discussion here on the boards, but I'm sure it's been thought of before. It was mentioned in relation to another thread and I decided that the discussion of having 4 ARs belonged in its own thread, so here goes... There's been alot of discussion about having 2 center referees -- some passionately for it, others passionately against it. However, rather than having 2 CRs on the field, what about having 4 ARs. However, the additional ARs would not have ALL the same responsibilities as the current ARs. What if... The system would be fairly similar to the diagonal system of control. First, terminology-wise... For the two ARs that are in the current position of the ARs, let's call them Senior ARs -- SARs. For the two new / additional ARs, let's call them Junior ARs -- JARs. In this situation, Senior and Junior mean nothing about experience or capabilities, it's just to be able to distinguish between the for discussion purposes. Under the 4 AR system, the SARs continue to do everything they've always done EXCEPT call offside. There is no need to stay with the second last defender, they just need to stay in the best position to do their other jobs -- they call the ball out of touch, over the goal line, assist on fouls in their "area of control", etc. The JARs do NOTHING but call offside. They don't need to worry about anything else. Their sole purpose for being is to stay with the second last defender and make the offside call. Some might protest that this is worse than having 2 CRs because now you have 3 people calling fouls, etc., but I don't think so. There is still only 1 referee in charge. He would have the right to waive down the AR under this system just as he current can. He can delegate whatever level of authority he'd like -- primarly by defining the "area of control" for the SARs. You have no overlapping of responsibility between the ARs on same side or on the same end. Also, the CR could more easily let play become further away from him when in the SAR's area of control -- he doesn't need to worry about the SAR missing a foul because he is looking for offside -- which happens. OK, what do you guys think?
