question about B team that my board created

[shakturi101]

I am playing as RB Leipzig and at the start of the game Leipzig does not have a number team (only a U19 team). However after my season ended the board offered to create a II team and I said yes since I did not have a good development place for my young players that turned 19 so I was loaning everybody out. However, I see that this team is semi-pro, so I when I put all my players that I want to develop, they are only practicing like three times a week for two sessions. Is it worth it all to put players on this team, as they will not develop very well only playing three times a week? I'm not really sure who to put on this team. Any ideas on what to do?
