A weekly look at what the Kansas City Chiefs must fix:

The Chiefs are one of four teams yet to force their opponent to commit a turnover. That’s one reason the Chiefs are 0-2 going into Sunday’s game against the Dolphins in Miami. Their defensive system is based on pressuring the opponent into making mistakes, and the Chiefs have failed in that regard so far. The Chiefs’ pass rush has otherwise been productive. It has a sack on 8.5 percent of its opponents’ pass attempts, which ranks eighth in the league. In their 9-0 start last season, the Chiefs led the NFL with 23 takeaways and five defensive touchdowns.
