1. I think being able to use funds from early bids mainly benefits those with friends in the game (in this case, countries) that they can ask to bid on one of their players so they can go bid on another player/staff. But I get Mod-CrazyEye's point too.
2. If you have to play the players salary at the outset or during the week, won't it just reduce the transfer bids by approximately their salary? Instead of paying 1.2 mil for Silvas, BK Tikums would probably have been able to get him for ~0.7 mil instead.
3. If this was the only thing done, this would only address it for BBB, and would just reduce the options available to those who want to make a run at the championship if they find themself in a rare situation to win.
4. I really like this idea, it reduces the 1 game rental players in all facets without limiting manager's options. And the justification to do that based on happens irl is that players need time to adjust to their new teams and settings. Makes things slightly more complicated, but I think in this case, it'd be worth it.
just my 2 cents.
