So is Chilly right about this?
Childress berated referee Bill Leavy, noting an NFL rule that requires officials to allow teams to match another team's substitution. According to Childress, officials should not have allowed the Redskins to snap the ball until the Vikings had a chance to complete their substitution.
"My understanding of that rule and all the memos that I've seen is that a guy should get time to match the personnel," Childress said. "It was clear what the intent was. It was a challenge-able call and they wanted to snap it quick. Most of the time when that happens there is no personnel change, but in this case there was."
Childress said the procedure was a "point of emphasis" during offseason discussions.
"It cost us a change of possession and it cost us momentum in a big football game for us," Childress said.
