Bear Market—Trending DownPoor football officiating: Duke had a chance to shock No. 7 Louisville on the road Friday, and the outcome of the 24-14 Cardinal win could have been different if not for a questionable call early in the third quarter. Louisville quarterback Lamar Jackson found tight end Cole Hikutini on an out route deep in Cardinal territory, and Blue Devil sophomore linebacker Ben Humphreys appeared to cleanly strip and recover the ball inside the Louisville 20-yard line. But instead of Duke taking over with a chance to take the lead, the officials ruled that Hikutini's forward progress had been stopped even though no whistle blew. Following the sudden change in fortune, Cardinal running back Jeremy Smith exploded for an 80-yard touchdown run to put Louisville up 17-7.The questionable calls extended to the professional ranks, where officials missed a clear pass interference call on All-Pro Seahawks cornerback Richard Sherman. The no-call decided Seattle's win against another NFC power in Atlanta, and was another example of bang-bang calls or no calls potentially having a major impact on the outcomes of games.
