I'm not sure why my point is so hard to understand. Most every other team starts next season with a cap of $82.5M. Vegas essential now has a cap of $90.375M.
End of the day this is a positive for them or they wouldn't have done it.
You could acquire every LTIR contract in the world and start with $120 mil cap and it doesn't make one difference in the lineup you're able to ice.
The only positive for them is that they're able to dump Dadonov's contract without paying any assets to a team that will be on his NTC list in a few weeks. They'll be dumping Weber's contract to a team like Ottawa or Arizona trying to reach the cap floor next year.
