It's a week after the fact, but the Broncos don't have a prayer of convincing many in the team's rabid fan base that having Peyton Manning take a knee late in the fourth quarter of a tied playoff game was the right move. Count Hall of Famer Shannon Sharpe, a former Broncos tight end, among those taken aback by the decision by coach John Fox in the Denver-Baltimore divisional-round game. "I was very surprised," Sharpe said. "That's Peyton Manning. John Fox has never had a Manning. He's had only marginal quarterbacks. He may have to change his thinking."
