The 49ers took advantage of their opportunities early Sunday.
Marcell Harris recovered a muffed punt by New Orleans Saints return man Deonte Harris, which the 49ers eventually capitalized on with a 32-yard Robbie Gould field goal, giving the 49ers a 10-0 lead in the first half.
Just about everyone had the Saints winning handily Sunday, but the 49ers are showing they won't just roll over early at the Mercedes-Benz Superdome. Nick Mullens found rookie Brandon Aiyuk for a touchdown on the 49ers' first drive to take an early lead.
New Orleans was scoreless through one quarter against coordinator Robert Saleh's 49ers defense.
