From Ian O'Connor's story on Peyton Manning's mother's wish: "Olivia Manning had spent one lifetime watching her husband get battered on the football field, and another watching her middle and youngest sons absorb their fair share of abuse. As a mother who had watched Peyton endure 18 seasons of hits, not to mention four neck surgeries that left him unable to throw a 10-yard lob, she was the right person to ask whether Peyton, now the 39-year-old two-time champ, should end his epic career right then and there."

From Dan Graziano's story with bold predictions for the 2016 season: "Just because Rex Ryan's emotions are one of Bill Belichick's favorite chew toys, the Patriots sign defensive end Mario Williams after the Bills cut him and he collects 14.5 sacks."

From Bill Barnwell's ranking of the reasons for a Super Bowl 50 upset: "I didn't think that [DeMarcus] Ware and [Von] Miller could come up with something to match their career day against the Patriots two weeks ago, but truthfully, they weren't far off. Ware and Miller combined for six of Denver's 13 knockdowns of Newton. This Broncos pass rush has taken things to a new level when Denver needed them most."

From Mike Sando's story on why quarterback Brock Osweiler should stay in DenverInsider: "As Osweiler plots his future, he should weigh what role an especially strong defense could play in winning games. He should weigh what role winning games might play in his own ability to remain a starter. He should weigh what role remaining a starter could play in earning another contract down the road. Osweiler did lose his job this season despite having Denver's defense on his side, but Manning's outsized presence on the roster made this a unique situation."
