Dallas Cowboys owner Jerry Jones on the possibility of drafting a quarterback to backup starter Tony Romo: "We're going to try to all the ways - all ways - to come up with a way to get Tony a backup. ... Everybody wants that, but we have a high draft pick, obviously. We're earned it, and we've got it. If we evaluate and get an opportunity to get a couple of players there, we got to look at it hard." More from Todd Archer.
Who's going to get the NFC's No. 1 overall playoff seed -- the Carolina Panthers or Arizona Cardinals? And what are the consequences? If the Panthers fall to the No. 2 seed, their chances of winning the Super Bowl drop to 16.4 percent and the Cardinals' odds of winning the Super Bowl rise to 21.9 percent. More from Aaron Schatz on the projected playoff brackets.
Peyton Manning was all bundled up on the sideline for part of an ice-cold Monday night, and he had to be wondering how his endgame turned so ugly and cruel. If he's telling the truth about the Al-Jazeera report that he started shredding the other day to ESPN's Lisa Salters, then he deserves so much better than what he's getting now. More from Ian O'Connor.
Why has Carolina's Ron Rivera had a better season than any other head coach? He has a clear vision for how he wants the Panthers to play on both sides of the ball. He survived a change at general manager after the 2012 season, and managed to keep a unified team pointed in the right direction amid cap-driven tweaks to the roster. More from Mike Sando on ranking the best NFL coaches this season.
The Tennessee Titans remain the odds-on favorite to get the No. 1 overall pick in the 2016 draft, while the Baltimore Ravens' win vs. the Pittsburgh Steelers in Week 16 will loom large come draft time. More from Kevin Seifert.
From ESPN Stats & Information research: The Eagles led the NFL in average yards per play in Chip Kelly's first season, but ranked 11th in 2014 and 24th in 2015. One of the biggest issues this season was the Eagles' quarterback play, after swapping out Nick Foles for Sam Bradford in the offseason. Bradford's 37.5 Total QBR ranks 33rd among the 35 quarterbacks with the most action plays this season.
