It would be interesting. Certain leaders would entice certain players. If they wish to come over the leader would have to drop a certain amount of money based on the players worth. An actual system would be in play. Trading, loans, etc. could get fun.
This would be assuming that an excess or drought of players were available. So say TNWL says you will play a minimum of 10 players and a maximum of 15 during a battle. Lower tier teams would then reach out to the players that do not get the playing time they wish; seeing that only 15 plays can play at once.
In the higher tiers there would be bidding wars for the best players. But in the end it would all depend on whether the player wishes to leave.
