I had a team in 7Mickey7 once that was tied for the best record in the world at the half way point, and then proceeded to drop something like 37 of the next 42 games. Squeaked into the last wild card, but I still have no clue....
The team I gave up in Canseco did just about the same thing, only worse- going from 91 to 85 to 79 wins when I was certain it was getting (much) better in terms of ratings. To top it all off that last season, after coming from something like 14 back the second half, was 3 up with 3 to play and dropped all three. Go figure.
