How to get a weak league?

Thanks a lot for this explanation. And thanks Tzzz for the question!
I assume this also includes the rating of my team in FA. This is my second season and i found out that my team has way more stars in FA than my default squad lineup. So i guess this rating includes the 2 140%s I hired from youth academy, whom are garbage anyways and sitting in my reserves.
