No sir. He'll have the created face you made for him.
Basically they way it will work is whatever roster is in your save file will be the same roster carried over. No new face scans no updated rookies etc.....
Example:Brandon Finnegan will have an updated SCEA scan/Model in MLB 15. If you use a carry over save from 14 he will not. It'll be the same created player from your file in 14. Does that make sense?
If you want updated scans/models for players you'll have to start a brand new franchise in 15.
