I would suggest to handle national team information like normal league team information in the bbapi, so everybody can read information like teaminfo, teamstats, standings and roster (without the hidden skills)..
Only the current nt coach can see the hidden inforamtion, skills and so on.
For the nt scouting by the nt coach teams still need to give player information manually or over scouting sites like
