Everything in that video is accurate but is an oversimplification of the issue.
1) yes the cowboys have the lowest payroll in the league but they are just a Ceedee Lamb extension from being towards the middle. A dak extension would likely put them towards the top.
2) signing guys earlier is what the cowboys should be doing I agree completely.
3) they almost always pay high signing bonus money. Daks last contract they paid him $75m year one to keep the cap number down. That still doesn’t make the cap number go away though, you’re just pushing it back.
Signing all three of these guys does create a tight cap moving forward, Jerry is spot on about that, his 80% numbers are just inflated as it’s closer to 50-60%
