4. The inside linebackers have to get better
With all of the talk about losing Peyton Manning and Brock Osweiler, the Broncos might have missed inside linebacker Danny Trevathan as much as anyone on Sunday.
Brandon Marshall, Todd Davis, Zaire Anderson and Corey Nelson combined for 14 tackles on Sunday but Falcons runners racked up 122 yards on the ground.
And it wasn’t just the running game. They were beaten in the passing game too.
Running backs Devonta Freeman and Tevin Coleman combined for seven catches for 167 yards and a touchdown on Sunday.
That just isn’t good enough defense from this group.
