gets a guaranteed multi-year contract. Sure that could include some games in the G-league like Bronny has done this year and other players have done in the past, but that is for a guaranteed contract.

If he might be late second round or not guaranteed second round, then the reasoning for one more BYU year becomes stronger.

What opening post is saying, that if the draft projections at 32 are accurate then he will already be past a 2-way deal. The players on 2-way deals can be cut anytime. Being drafted at 32 he'd have a multi-year guaranteed contract.
