I found this:
Once you have picked 15 on field players and 7 substitutes, a submit button will appear at the top of the screen. If you enter your team before the transfer amnesty closes, you will not see a submit button. If your team is completed before 01:05 (EDT) on 16th February, 2014 it will be automatically submitted. Your team will not start scoring points, nor will it appear in a Private Competition, until it has been submitted.
But still no where can I see anything specifically mentioning transfering players from bench to play etc.
