No good things happen by surprise in BB.
My team is quite good for its level, so I expect to win and a loss is a downer. Even the one time I expected/planned on losing, I won (on the road, playing TIE versus CT) and thereby didn't play a game 3 in the finals and missed out on a fine payday.
I hope for pops, and when they didn't happen, it is unpleasant bit of news.
Injuries are, of course, the worst. They knock out training, the part of the game I like the most. They 'expected' duration of the injury is always longer than the forecast, so that's crappy bad news, too.
I think this is a bad situation for BB, that is, no serendipity ever occurs (yes, lousy teams pull upsets, but I don't care about that).
I have some ideas about goo0d luck, but quite frankly I don't expect to be playing after this weekend, so I 'm not going to mention them.
