Help me out Please

I haven’t played the show since 2016 and I am kind of completely lost with 2021. Is there a place I can read about all the changes ? Can you not use stubs to upgrade your skills anymore ? I can’t seem to find the place to be able to. Also why am I being forced to be a pitcher and pitch a game when I am a catcher, I am so confused.

No longer can you use stubs to upgrade attributes. Attribute progression is now drawn from your play.

It’s an all new RTTS system this year, even different to the 18-20 version, which differed to what you’re used to. We’re all new to it.

How did you pick a catcher? I can’t figure it out.
