Denver knows quarterback switch isn’t team’s only fix

ENGLEWOOD, COLO. » The Denver Broncos’ locker room is abuzz over Brock Osweiler ‘s promotion after Trevor Siemian’s dozen turnovers cost him his starting job this week.

They know Siemian’s poor play wasn’t the only reason for their 1-4 tailspin that’s threatening to waste another elite Denver defense. They have plenty of corrections to make if they’re going to avoid their first four-game losing streak since 2010 when they visit Philadelphia on Sunday.

“Absolutely, football isn’t an individual sport, it’s a team sport,” tight end Virgil Green said Thursday. “Yeah, we’re bringing Brock up to do things, but we all know that Trevor is totally capable. We just need a little more from everybody. Not just one position, every position.”

Coach Vance Joseph lamented this week how Siemian’s three ugly interceptions nullified another outstanding defensive performance in a tough loss at Kansas City on Monday night despite bet- ter blocking and rushing effort.

“The run game was fine but I played terrible,” said C.J. Anderson, who had 78 yards on 15 carries. “I didn’t score and missed some opportunities. That’s on me. I just have to get better. The a 177-yard scouting report says I’m not a home run threat. Let’s prove them wrong.”

That task will be daunting when the Broncos (3-4) visit the NFL-leading Eagles (7-1), who sport the only run defense in the league that’s better than Denver’s.
