You're completely missing the point.
If you draft Jeanty that's going to require you to use your 9th overall 1st round pick.
If a guy like Skattebro gives you 70% of what Jeanty does and you can grab him in the 4th, that means you can use your 9th overall pick on someone else in a bigger position of need.
This is part of the reason RBs are devalued so much high in the draft. The Giants drafted Tracy with the 166th pick in the draft and he gave them over 1100 yards from scrimmage. 100 yards less than Barkey in 2023 whole having a higher ypc.
2023 Barkley: 1242 yards from scrimmage. 3.9 ypc
2024 Tracy: 1123 yards from scrimmage, 4.4 ypc
You can't look at that and tell me you can't see the value problem with selecting a RB high vs later in the draft.
