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.
The England vs. Belgium game in June will feature the Hawkeye system used at Wimbledon. That system is fast and has become a hit at Wimbledon. Imagine the crowd at a Derby cheering as the system shows a potential goal or no goal. It would be really fun.
