Definitely try being a lower down team. I'm playing as Wimbledon and have just started my second season. I just missed the playoff positions in my first season, but it's made me more determined to get promotion this year. It's such a good feeling beating a team in a higher league than you in the cup. Or clinching a deal for a player that's much better than your squads average standard.
Even when you're losing, you've just got to stick with it, and it really does pay off.
