But at some point, the second contract is really not related to the rookie contract, as you aren't required to pay these guys. Jalen Green's second contract will a reflection of his market value based on his performance during his rookie contract, not merely scaled to his rookie contract.
Jalen Smith is a good example of this - his performance didn't warrant that big second contract despite being a lottery pick. Mo Bamba another good example - his earnings have slid backwards as he's just not proven to be good enough for a big second contract.
We'll see this offseason at what James Wiseman commands. My guess is that the AAV of his new contract will be significantly less than the $12MM he is making this year on his rookie scale deal.
