Multiple Teams in Franchise Mode

Normally, choosing "Coach" is what allows you to control the entire team, as well as every player on field in the game. There's a setting under "league settings" before you start a franchise that says "full on-field control" which SHOULD allow you to control all the players. 

I find it odd for the game to work this way. Worst come to worst, just choose "coach" for your daughter and see how that works. I know that in years past I always chose "coach" and have always controlled my entire team while playing. I'm starting one now to see if this works, and hopefully it does. I normally start with multiple teams to fully customize fantasy drafts so I do a lot of trading after the draft is over. Again, if you're still having trouble, just choose "coach" and hope it works.
