Five lessons from last week:• College football rankings are for entertainment purposes only.
• The Orioles and Royals turn a best-of-five series into their best for three.
• Defenses need to pay attention to the Broncos’ Demaryius Thomas, or at least more attention than paid by the Cardinals.
• A 25-point lead isn’t safe in the NFL – for the Titans.
• The Kings will need fewer fouls (five) and turnovers (five) from center DeMarcus Cousins.
