Moving on: Denver Broncos

Here are some areas the Denver Broncos need to focus on after a 37-6 home win over the Oakland Raiders on Sunday:

Recap: After close calls to undefeated Atlanta and Houston in Weeks 2 and 3, the Broncos demolished the Raiders. Denver pulled away from Oakland in the second half, outscoring the Raiders 21-0 in the third quarter. Denver is 2-2 after its most complete game of the season.

Biggest area to fix: First-half play. The Broncos struggled badly in the first quarter of their two losses and led just 10-6 Sunday.

Biggest area to build on: Peyton Manning. Denver was good in all phases Sunday. Manning has been mostly good in the first quarter of the season. But he was brilliant against Oakland. He was clicking with his offense and he picked apart the Raiders.

What to watch for: One of Tom Brady’s favorite former teammates is expected to play a huge role for Denver at New England on Sunday. Center Dan Koppen was once Brady’s center and now he is Manning’s center. Denver's starting center J.D. Walton broke his ankle in the second quarter Sunday and he is expected to be out for the season. Koppen was signed after Week 1.
