From a game point of view, what is currently 'Impossible to sign' should be recoded to an algorithm that:

1) Names a high sum that is a big chunk of one's budget. This number could be as high as, for example, ten times his "I'll sign for that." figure.
2) You get an email from your owner saying "No way. But I'll authorize up to $BigChunk-RandomPercentage"
3) You pick a number, knowing he might be willing to sign for a tenth, or you may not be able to match it at all.
4) The game compares you offer to the "I'll sign for that" figure and if it is that or more, he signs.

This means you will suffer the 'Winners' Paradox' penalty in that you most likely grossly overpaid for the player if he signs.
