The Seahawks fell in the Mile High City.

Despite first-half heroics from rookie tight end Will Dissly and a 51-yard score by receiver Tyler Lockett late in the fourth quarter, Seattle dropped its season opener to the Denver Broncos on Sunday, 27-24.

The big story was the Broncos' dominance in the pass rush. They sacked quarterback Russell Wilson six times. All-Pro linebacker Von Miller had three of them, as the Broncos rolled all over the Seahawks' offensive line -- a major point of concern the last few seasons.

Wilson completed 19 of 33 throws for 298 yards, three touchdowns and two interceptions in the loss. Dissly, making his NFL debut, opened everyone's eyes with a three-reception, 105-yard performance with a touchdown Sunday.

Making his Broncos debut, quarterback Case Keenum completed 25 of 39 pass attempts for 329 yards and three TDs with three picks. Denver's rookie running back tandem of Royce Freeman and Phillip Lindsay dominated in the backfield for a combined 30 carries and 142 rushing yards.

But how did Earl Thomas look in his season debut, just days after returning to the Seahawks? Did Shaquem Griffin do anything spectacular in his first regular-season game? What about rookie cornerback Tre Flowers?
