I’d agree with that. We’ve been relegated to the equivalent of the Third Division three times since I started watching the club in 1963 and each time our stay in the third tier lasted just one season. In 75/76 and 82/83 we were promoted straight back and in 85/86 we suffered a second consecutive relegation. That goes to the heart of my belief that relegation doesn’t have to be a disaster and to why I’d accept the scenario outlined in the OP apart from the bit about it taking us five years to return.
