I'd be gutted. The last automatic promotion was 1984ish and its the one thing I want to see. Not popular but I do find some play off successes a bit false as you can finish closer to 14th than top and still get promoted.
To get automatic usually means that you've won loads of games and generally been good to watch, basically you can yourself the best, and not to be there is shite.
My ideal situation, and realistic, would be to finish 8th this season, then have a packed Bloomfield Road next season to romp to automatic. It all feels a bit false to me at the moment - match day is spending hours with family and friends, having a crack, bit of a sing song and the atmosphere. I've not felt elated or gutted once this season.
Maybe it because I'm not of the many fans with a second team who has a second team so don't get the armchair supporter thing. Whereas our liverpool/United fans are used to the current experience.
Saying all that I wouldn't complain if it did happen and we got promoted this season.
