There really isn't much of a bidding process at all. I am not 100% on the rules, but teams aren't really allowed to provide things outside of their players. You can't pay them, you can't promise players to rehab there, pretty sure you can't promise them exhibition games at their ballpark, you can't promise to place certain players there...etc etc etc. Either the affiliate wants you or doesn't. Their decision likely comes down to record, possibly how good of prospects you have coming up, and if they believe they can market off of the players coming through down the road. Sometimes minor league owners and an MLB owner know each other and that can give them an advantage. In the grand scheme of things the affiliates could flip a coin and not be effected no matter who it is. Their money maker is fan experience not exactly how good the team is. People will say win-loss doesn't mean anything for the bottom line. That may be true, but if it doesn't matter either way do you want a 80-60 team or a 50-90 team?
