They don’t say “if you are there 40 picks later, are you asking for this”
they ask “what number do you need to get to, to get signed?”
they say “3 million” for example and twins agree.
then the players agent tells other teams that “$3m is the amount it will take for the player to sign” and if they don’t want to pay that, he falls the extra picks.
that is how Brock porter fell. He agreed to a number and the rangers were only one that could get to the number because they saved on rocker up front.
