Monster's presence as the title sponsor isn't the important factor. They are reported to be paying $20-$25 million per year and are only signed through 2018. I would guess that most analysts believe it is a distinct possibility they won't be the title sponsor by 2020, let alone 2024. If they go away, another company will replace them and may pay even less. But even if that amount was $5 million annually, this is not the revenue that is propping up the whole enterprise. That would be the $700+ million of annual TV rights money that is locked in.
