The NFL will look into the inadvertent whistle rule that required officials to give the ball back to the Broncos in the final seconds of Sunday?s win over the Chargers, according to New York Daily News. Greg Aiello, league spokesman, said the NFL competition committee will look into the rule this winter, perhaps changing it as it did the "down by contact" rule. "Officials are held accountable for their calls. They are graded on every play of every game," Aiello said Monday. "Ed [Hochuli] has been an outstanding official for many years, but he will be marked down for this call. Under our evaluation system, an official?s grades impact his status for potentially working the playoffs and ultimately whether or not he is retained."
