Trading down works, but I think most of the draft capital we'd acquire would be for the following year. As an example here's what SFO gave up to jump to 3 from 12
2021 first-round pick (No. 12 traded to Eagles)
2022 first-round pick
2022 third-round pick
2023 first-round pick
Which is why Denver is the ideal choice, as they have 2 2nds. So theoretically we could do a deal that looks like one of two options
Jets receive 9, 2022 3rd round pick, 2023 first rounder
OR
Jets receive 9, 2022 2nd round picks (40 and 60) and a 2023 mid-late round selection, most likely a 4th.
I don't think we get anywhere near what the Dolphins received last year, but anything is possible, and JD has gotten above market value in literally every trade he has made.
