In league games this season, we've had the exact same amount of FTs, suggesting our players are equally good at drawing fouls. And your team has averaged more fouls per game, suggesting they are more foul prone. So I doubt it was your players that contributed to it, was just the luck of the draw. The players of mine that fouled out aren't exactly super foul prone either - heck Wayne has fouled out I think three times in the past five seasons...
But that's the way it goes - I had a good draw to get to the final in the first place, so you win some and you lose some. Just rather annoying to get my tactics for the final bang on, only to get screwed over in the worst way.
