Two team still train 12, not 6. While it is the case now, that's one of teh reasons you can't buy your players between teams (mostly to prevent cheating).
I said 6 players each team.
I draft a player, send him to Utopia to train with 7/7 coaches, and send him back while still being broke in first team
As I said there can be rules put in place to mitigate any overwhelming advantage. Player can't participate in playoffs that season, or in the main team. This will make it that teams will use it purely for training players.
The whole premise is to treat the 2nd team as a development league (G-League). I really don't see the overwhelming advantage or "Pay 2 win" aspect you're talking about.
believe training adds complexity with sacrifices to the game and this suggestion takes it away.
There's a lot of talk about how training players is expensive and becoming harder and harder to see benefits. Let's be real, with the current market you can easily pickup div II and III players for peanuts. So I believe we should be open to suggestions like mine (even if my suggestion is not taken).
