Yes, forfeit the pick. Exactly.
Reality is the point has been explained and you just choose to ignore it. But we'll do it again.
Every position carries a value in the NFL. QBs are paid more than kickers, OTs are paid more then OGs, DEs are paid more than MLBs, etc. Within that framework, teams build their salary structures, etc.
The moment Elliott gets picked at 4, he's a top ten paid TB. They take Bosa at 4, for example, he's now like the 35th highest paid edge player in the NFL. You can try to poo poo it but there is value associated with the salaries you pay guys. So if Bosa turns out to be a stud, for example, you have him for 5 years at a mid-level market rate. Elliott is being paid like an elite TB from the start.
