As a Chiefs' fan, this says it all.
As far as running Henry, Bishop, this was probably the combination of the Chiefs defense containing him and the expanding lead by the Chiefs necessitating a change in the Titans game plan.
Henry had three carries for seven yards in the second half. All were on the Titans first possession of the second half. He had sixteen carries for sixty-two yards (3.8 yds per carry) in the first half. That includes twenty-four yards on two carries.
The Chiefs loaded the box. He is not great at getting outside nor is much involved in their receiving game or long third downs. He had only eighteen receptions in sixteen regular season games.
After scoring touchdowns on their second and third possessions of the second half, the Chiefs had an eighteen point lead before the Titans had only their second possession of the second half.
