The Denver Broncos and Indianapolis Colts are facing significant challenges early in the NFL season. The Broncos' offensive line struggles and rookie quarterback Bo Nix's poor performance have led to a 0-2 start, with head coach Sean Payton reconsidering the offensive approach. Meanwhile, the Colts' defense, led by coordinator Gus Bradley, has allowed 474 rushing yards in the first two games, the most since 1978, causing Bradley to take responsibility and seek improvements. Additionally, the Miami Dolphins have dropped in power rankings after another concussion to quarterback Tua Tagovailoa and a loss to the Buffalo Bills, highlighting both offensive and defensive issues.
