Playing Be a Gm on medium difficulty. In my 9th year out of 10. Built a really solid team, and I simulate the year, it goes really well for me. I don't play any games, and my team ends up 60-12-8. Get to the playoffs, and I'm playing a team that barely squeak in. I don't make any changes, sim the first 3 games and go down 3-0 after losing 5-3, 7-2, and 4-1.
F***ing stupid. >_> It happens every year too, though usually not as drastically. My teams just fall apart in the playoffs.
