10 Biggest Questions: What roles will the Chiefs’ linebackers play?

Heading into the Kansas City Chiefs' season, I'm continuing my "10 Biggest Questions" series about the team. So far, we've covered seven questions:

• What is the Chiefs' contingency plan at offensive tackle?
• Will Deneric Prince or Clyde Edwards-Helaire crack the running back rotation?
• How far along are George Karlaftis and Felix Anudike-Uzomah as pass rushers?
• Do the Chiefs need to add another defensive tackle?
