My fault that I did not read that you want to get rid of one training slot (which game of the week) - just to add one for the D-league. WHAT A GENIUS IDEA.
No seriously - what a messy and useless suggestion. Only for DIV I and II, get one training, give one. What for?
You could argue that it would be interesting to see something like we have in european soccer, where big teams hold "amateur" or "B" clubs in lower divisions just to develop their prospects. That would be a pretty complicated but interesting approach, that could fill lower leagues.
