You need your head checked to think relegation would be good for us, it could finish off the club.
If you look at it as a dying relative and want to end their pain then that's fine, if you want to keep it in your life then turning off the life support when its in a coma will no doubt see the end of the sorry story.
it could finish off a club with now relatively little debt(go on force yourself to say thanks to Ashley for that) a huge stadium and 50k tickets sold a week to make money from. If they can even keep it half full they can make more than almost any other club in the championship and more than several premiership teams.
You'll see the end of Newcastle if they go down? melodramatic much......
In all honesty you can only pray that relegation will cause crap clubs to do the all too common thing of buying "experienced" premiership players and take Barton, Butt,Smith off your hands leaving most likely a LOT of spare wages to go on a lot deeper and better squad of actual quality players rather than players who USED to have a reputation. A good squad clear out and buying cheaper, lower wage and better players will do Newcastle no end of good.
You've also got to remember something else the Ashley haters, he's still paying off transfer fee's for players not bought while he's been in charge. As is more and more common rather than pay upfront people agree to pay 1-2mil every 6 months for a few years which is also effecting who you buy and how much you can spend. THe debt isn't officially as you don't "owe" it yet, but Ashley is paying off essentially the mortgage of crap deals from previous owners.
Theres basically no way in hell Newcastle will run into financial trouble once run efficiently and stupid managers don't just buy end of career high wage players who can't be bothered(the viduka's and the like), once you stop spunking huge money on players who are sicknotes, etc.
Stadium capacity has ALWAYS been the key to making money in football and Newcastle have an advantage on what, all but maybe 5-6 other clubs in the country.
