And yet the Broncos have to scratch and claw every week because of the most confounding offense in the league. Through five weeks, the Broncos were ranked as the No. 1 defense in the league, with the No. 32 offense. This was the same team that set the NFL record in points two years ago. The same one that still has Peyton Manning, Demaryius Thomas and Emmanuel Sanders leading the way, with a proven offensive coach in Gary Kubiak. There was some concern about Manning's adjustment to Kubiak's offense in the offseason, but no one thought it would be like this. The running game improved in Cleveland on Sunday, but Manning had his worst game yet with many misfires and three interceptions.
