KANSAS CITY, Mo. The NFL was concerned that nobody could make it Sunday in Buffalo, where up to a couple of feet of snow was expected overnight. So, the league and New York officials decided to postpone the Bills’ wild-card playoff game against the Pittsburgh Steelers until Monday. They practiced all week in warm Miami, and it was 86 degrees on Friday, when they stepped on the plane to Kansas City. For you, me — it’s cold,” Chiefs coach Andy Reid said.
