"Another first for Career Mode is the ability to manage and participate in training for youth players for the first time - their training sessions will mostly take form as Rush mode games between young players - and youth models have been significantly updated. In fact, there's a wider update to player faces in general in the form of something EA is calling EA Sports Cranium, which uses machine learning to give players that haven't been fully scanned a degree of genuine likeness in the game - with examples given across both men's and women's players."
This is interesting too... Participate in training for youth players? I'm not sure what to expect, but I have wished for the ability to play youth games in CM, and perhaps this is a step on the road to that. Either way I'm happy to see them try to add some new things to Career Mode, which is the only game mode I'm truly interested in.
