If Mike's wants to screw a world he's leaving, he can do that now. Offer $5M to a crap FA. He doesn't need to make 74 other offers. He's trying so hard to defend his idea he's not thinking clearly. Allowing us to overbid our budget doesn't give Mike a new way to screw the world on his way out. He can do that now.
The system I'm trying to explain would work fine if no players signed for a few days at the start of FA. If no players sign, there is no market value. The market is set when a deal is make, not when offers that can be pulled at any time are being tossed around. So Mikes 75 offers don't impact anything. At whatever cycle players will start to sign, one will take Mike's $5M. The rest of the offers go away.
If we can get a message that says we were over bid, we can get one that says our offer is now the best . Or a message that says that the offer we pulled is looking pretty good now & would we consider putting it on the table. Just like it works in the real world. None of it is complicated logic.
Just like in the real world, some players would act fast and grab an offer before it's pulled and some would wait longer. MLB teams overbid their budget and it works that way. Would work fine in HBD if the process was changed.
Easy enough to set it up so players with a lot of offer move slower than players with few. If Mike offers $5M to a player asking for $1M, and that player has no other offers, or one offer at $1M, then that player should jump on $5M right away after whatever no signing period there is.
So long as everyone has 36-48 hours to get in a bid, the system is fair. If you want a player, don't low ball. That's how it works in the real world with any offer. Make a low offer & someone might beat you. Make a high offer, and you might pay more than you could have if you slowly raised your bid. It's the way negotiations work.
It wouldn't be hard to add logic to penalize the kind of moves Mike's threatens. There could be a maximum number of offers that could be out at one time (not a maximum dollar amount, so long as no one offer is over what can be spent). Too many pulled offers could trigger a 1-3 day nobody will sign with you situation, as word would get to agents & players that you're wasting their time with offers.
The current system can be gamed in several ways. I think a lot of them have been mentioned, so they don't need to be repeated. I'm don't mean to criticize Mike, but I think he's figured out the current system. He doesn't win them all, but he knows the tricks and he's online all day almost every day so he he wins a lot more than his fair share. So he wants to maintain that system. If the system changed, he's might not win the bidding as often as he does now.
