I think it's really hard to compare apples to apples with this.
Today, is it realistic that you can get Ed Davis and Tyler Zeller like talents to be ok with coming off the bench as freshmen? I'm not all that sure. Even the rookies that were 5* and didn't play like Isiah Hicks... I'm not sure if that's all that relatable today. Maybe playing for UNC still means that much, but I have my doubts.
The other thing that needs to be considered is the NBA rookie wage scale. In 2006, the #1 overall pick was making less than $4M/year on their rookie deal. The last pick in the 1st round was making less than $800K/year on their rookie deal.
The 2004-25 rookie NBA wage scale has the #1 pick making $11M/year and the last pick in the 1st round is making just over $2M/year. And yes, that far exceeds inflation and far exceeds the purchasing power if you convert 2006 money to 2024. There is much more value in NBA contracts today and that obviously becomes even more significant if the NBA players are able to get second longterm contracts.
It's really hard to compare Roy's days to today.
For Hubert, it will come down to a few pretty easy things. If he's a good evaluator of talent and a good developer of talent, then he will have more margin for error for the type of player he can bring in. He can be more stubborn for lack of a better word. If he isn't, then he will need to pay for more talented players.
