Watch what other teams are doing. Odds are, some will lose a few games that you don't expect and might open a door for you. The season won't go exactly like you think it will. Pick your spots, try to steal a win here or there when you can. Look at who's your competition for the 8 spot. If you can somehow beat them heads up, then you've got a step in the right direction. Be looking at who's 6 and 7 on the other side. Especially when later in the year you are thinking about buying a player. Not finishing last, and then beating the team from the other side in the relegation game is all you need. You can look plenty ugly on the other nites and still stay up.
Or, if it does seem totally hopeless, you can just train young guys all year long and save money. You already know you can win enough at the lower level to advance, and you can be a lot better the next time around. On that path, you are mainly looking a couple years in the future for what you need to stay up the second time around. Saving money for two years and training up young guys can make that look pretty good I'd imagine.
My HT soccer team is facing pretty much that same spot. But, I'm finding it fun to try to plot my way into making it work for me in the long run anyways. ;) My BB team somehow did stay up last year (finished 6th and won relegation series), so its now becoming a problem of how to build a good team at this next level. Although, staying up isn't completely certain this year. Just more likely than it was last year.
