Yes, that's my concern as well.
I think, at least for 2017, attribute changes should be solely/directly tied to training/coaching (here's hoping for a revamp!

) but having stats tie directly to a player's ratings has an opportunity to vastly change a player's effectiveness.
EDIT: Addressed by Victor...it's nonetheless something I'm kindly hesitant about and will be watching.
