Kind of see where Micah is coming from to a degree if he is just talking Premier League era (not heard him say it).
After our relegation in 1983 (which was a huge shock) our consequent relegations from the top flight weren't a massive surprise (certainly not to us blues) Going down to the 3rd tier obviously was.
With regards the other teams Forest were a fantastic side for a short period (late 70s, start of 80s) but have been largely unremarkable since.
Villa and Leeds certainly weren't averse to getting relegated and spending time in the lower divisions in the 80s themselves.
Obviously open to interpretation, but if Everton did get relegated his season I feel it would be the biggest 'shock '(not that Everton fans appear to be shocked at the prospect) since we lost to Luton on the final day back in 1983.
