Not sure that could be done with RFID. You would need to be able to resolve relative angle between multiple passive antennas (RFID only recognizes proximity) and adaptively move the transmitting antenna up down the pitch with the last defender. And then there's the problem of range, you need to do this at upwards 50 yards. GPS tracking might be a better option, but there's still too much variance in its positioning and isn't dynamic enough for the situation of determining offsides.
It's a tricky problem to solve with current techniques, but it's a fun one to ponder. With unlimited money, you could couple inertial sensors with a GPS receiver. But even then, the problem requires an accuracy of 2-3". Not even that setup can provide that kind of accuracy over 45 minutes.
