It really depends on who/when it is signed - if you are signing a player that is just drafted IRL and in our draft, then it's a little more regimented.
If you take an overager, wait two years and they've torn up the AHL.... I will make the offer reflect that despite them likely being signed for much lower IRL.
It can be hard to balance - as we only have those four rounds are constantly chasing players after they are selected.
I totally get what you are suggesting, and does play into consideration when looking at the offers provided.
