THIS is How you EDIT ALL PLAYER Names in Teambuilder..
Simple video that shows every step of the way starting here on the EA website and ending as a downloaded team on your console (where you actually edit all the names).

But you can only do this in dynasty.. so if you want to control more than one team you would simply have to play with those teams in “play now”. Yet there is no way to edit the players names outside of dynasty. This is a huge disappointment
