its all slotted pay now. (last year + a little interest %) so not hard to figure out.

here is article on how much Nkemdiche lost falling from 1 to 29. Not that Rueben was ever going to go one, but tenth was possibility.

He tumbled down the draft board, landing with the Cardinals at No. 29.
That fall cost Nkemdiche at least $10 million in signing bonus money. His signing bonus with Arizona was slotted at $4.4 million. Had he gone first overall, he would’ve received an $18.5 million signing bonus. Even at fifth overall, he’d have gotten $15.2 million.
The salaries and signing bonuses for draft picks have been slotted since the new CBA was enacted in 2011.
