Answer based on context:

Heading into the game, there was a lot of hype surrounding new Eagles running back Jay Ajayi who was traded prior to the NFL trade deadline. The Eagles looked to improve to 8-1 for the first time since 2004 as they took on the Denver Broncos. The Broncos named Brock Osweiler as their starting quarterback, replacing Trevor Siemian. The Broncos took their only lead of the game on an opening drive that resulted with a Brandon McManus 53 yard field goal. Despite missing tight end Zach Ertz who was out with a hamstring injury, the Eagles offense didn't miss a beat. On their opening drive of the game, Carson Wentz faked a handoff to newly acquired running back Jay Ajayi, and found Alshon Jeffery wide open for a 32-yard touchdown down the right sideline. Later in the first quarter, slot cornerback Patrick Robinson picked off Brock Osweiler on an intended pass to Demaryius Thomas, setting up a Corey Clement 15 yard touchdown reception, on a screen pass. The Eagles responded to another Brandon McManus field goal with a 27-yard touchdown connection between Wentz and tight end Trey Burton. Following McManus' third field goal of the first half, Jay Ajayi found the end zone for the first time with the Eagles, with a 46-yard touchdown run to close the first half. The Eagles led 31-9 at half time, and following a third quarter touchdown run by Corey Clement and touchdown reception by Alshon Jeffery, the Eagles led 44-9. The final score was 51-23, which was virtually a mirror of their last meeting in 2013, and Corey Clement finished the day with three touchdowns (two rushing, one receiving). With the win, the Eagles went into the bye week with the best start since 2004. They had also surpassed their win total from last season where they only got 7 wins. Furthermore; this was the third largest victory at Lincoln Financial Field since the 54-11 win over the Bears in 2013 and the largest victory in the Doug Pederson era.
