Not sure what you're thinking here.
Take a guy like Frank Nazar. Goes back to college in 2023-24, plays an entire season, goes to Frozen Four so season is extended. On April 13, 2024, signs an ELC, receives a full signing bonus, plays 2 games and NHL season ends. Now enters 2024-25 on a second year of ELC, rather than a first year, so he's quicker to a second contract and theoretical shot at more money without having to spend more time in the AHL to get there.
The signing bonus didn't poof away because of when he signed his ELC. Now let's say Michigan (huge school with big alumni and that likes sports a lot, and likes hockey) is giving a going rate of $125K for mid-1st round picks.
If 2023-24 is an AHL salary of $80K, the $125K of NIL wins out. The signing bonus (which gets spread out over the contract, not the entire contract value up front to begin with) is only delayed, not suspended, so uhh.. six month time value effect?
