For the record, I never thought you were whining or complaining about losses-- I think you have valid points. I wasn't aware of your prior BB experience, so I was just trying to offer some sound advice. In ragards to the undefeated team, if his arena size is lacking, he will get destroyed in DIII. You can't last when your opponents are making 100-200k more than you.
Also, the good thing about BB is that for up-and-coming managers can focus on developing prospects and their goals can be to get their prospect on the U21 team, or perhaps the national team, rather than promoting. Or they can focus on doing well in the tournament. Success comes in different ways while playing BB. Promotion will come with time invested; however, there are short-term goals that can be easily had.
I rememeber when I was new, I knocked out a DII team out of the tourney (I believe I was D4 at the time) and I got a lot of enjoyment out of his anguish. I was reading his league forum and he was ranting about the loss.
