Baltimore opened Week 1 with a 41-23 rout of Indianapolis, piling up 31 first-half points and averaging 11.1 yards per play over its first five drives.
Lamar Jackson looked revived in new coordinator Declan Doyle's scheme, while Zay Flowers posted 150 yards before a hamstring aggravation and Derrick Henry added balance on the ground.
Dallas landed on the losers list after a 28-20 defeat to the Giants, with coverage busts helping Isaiah Likely score twice and New York converting 9 of 11 third downs.
The Cowboys also surrendered 165 rushing yards and repeatedly failed in late-stop situations, an alarming start for a defense that had already been overhauled after 2025 breakdowns.
Elsewhere, Week 1 winners included Josh Allen, Chicago coach Ben Johnson and Cincinnati's takeaway-heavy defense, while Cleveland, the Chargers, Green Bay and Tennessee also stumbled.
