I discovered the performance shift, if you want to call it that, in OOTP 17 and haven't looked back since. Are we all really that bad at calling game activity? I think not.
Some of us are, I would imagine, are pretty good at emulating what we see when we watch baseball on a day to day basis. For whatever reason though, the game seems to penalize us for managing the in-game action.
Perfect example in this games iteration, I was playing one game per week with the Dodgers and with the exception of opening day, I was getting decimated while on the other hand when I simmed, I saw (box score) 10k's by Ryu (before he DL'd/Tommy John), 4 for 4 with 2HR performances by the likes of Rob Segedin, Logan Forsythe, Kike Hernandez...if I played, I was lucky to squeeze a hit out of Seager, Bellinger, etc.
So, as I found true in 17 and then 18, I will continue being GM in this years version as well.
