The Dallas Cowboys made the most aggressive single-slot trade-up of the first round on Thursday night. They sent the No. 12 pick, the No. 177 pick (sixth round), and the No. 180 pick (sixth round) to the Miami Dolphins for the No. 11 pick — a one-slot move whose cost was, on every published trade-value chart, an above-market premium. The pick they wanted was Ohio State safety Caleb Downs.
The arithmetic of a one-slot trade-up is normally simple. The Jimmy Johnson chart values the No. 11 pick at 1,250 points and the No. 12 at 1,200 — a 50-point gap. The two sixth-rounders are worth a combined 33 points. Net cost of the move: 17 points the Cowboys paid above market. That is a small number in absolute terms, and it is exactly the kind of premium teams pay when they have a single-name target and a fear of a slip.
The fear was real. Downs had been climbing every published board for six weeks. PFF moved him from 17 to 9 between the Combine and Pro Day. Daniel Jeremiah had him at 8 in his final mock. Inside the league, Downs was widely rumored to be the player the Atlanta Falcons (No. 14) were prepared to trade up for. Dallas's front office concluded that one of two things would happen if they stood pat at 12: Atlanta would jump them to 11 (Miami had been publicly shopping the slot), or Miami would take Downs themselves rather than trade out. Either outcome ends with the Cowboys taking their second-rated player at the position. Trading up one slot, at a 17-point premium, eliminated both risks.
The fit in Dallas is the cleanest part of the analysis. Downs is the most plug-and-play safety in the class. He played both deep middle (free safety) and box (strong) at Ohio State, ran a 4.41 40 at the Combine, and posted a PFF coverage grade of 91.2 in 2025 — the highest single-season grade by a college safety since Minkah Fitzpatrick at Alabama in 2017. The Cowboys' defense, after losing Trevon Diggs to free agency in March, has a positional vacancy at strong safety that no current roster player solves. Downs solves it as a Week 1 starter with three or four years of growth to come.
The downstream cost is two sixth-round picks the Cowboys would otherwise have spent on UDFA-class flyers. The bench-talent loss is real but small. The marginal probability of either of those two picks producing a starter, historically, is roughly 4-5% combined; the marginal probability that Downs becomes the Cowboys' Defensive Player of the Year candidate within three seasons is much higher. That is the math front offices run when they trade up. Most boards graded the pick a B+ at the slot; CBS Sports gave it an A- on positional fit. Our internal grade is A-.
The Miami side of the trade is also defensible. The Dolphins moved down one slot, picked up two sixth-rounders, and still landed their target — Alabama left tackle Kadyn Proctor at 12. General manager Jon-Eric Sullivan reportedly told ESPN that Miami had Proctor as the highest-rated remaining offensive lineman on its board and was confident Dallas wasn't taking a tackle at 11. If both teams got exactly the player they wanted, both teams won the trade — and that is the cleanest version of how the modern NFL trade market works.
