From Adam Schefter's story on the five biggest NFL offseason storylines: "This year's free-agent class doesn't include an Ndamukong Suh, a franchise-type player who is permitted to reach the open market without being tagged. On paper, a good group of players is set to become unrestricted free agents, but some will be tagged and others signed to long-term deals before their contracts expire."

From Bill Barnwell's Super Bowl preview: "The truth is that the Broncos aren't an especially great fit for this Panthers offense. You'd want a defense who can stand up in short-yardage situations, and the Broncos are the second-worst short-yardage run defense in the league, ahead of only Carolina. (Remember that when the camera pans over to Riverboat Ron before a fourth-and-short.) If you wanted to construct a defense that was designed to stop Carolina, you'd want penetrating interior linemen who could blow up plays in the backfield, rangy inside linebackers who could run with Newton and tight end Greg Olsen, and safeties who weren't going to get burned deep. That isn't Denver."

From Ian O'Connor's story on Broncos defensive coordinator Wade Phillips: "On the subject of valuable sidekicks, it seems Denver's best chance to upset the Carolina Panthers in Super Bowl 50 rests between the ears of Phillips, a wise, 68-year-old head who has come to terms with the fact that he was destined to shine in supporting roles. In fact, if the top-ranked Broncos defense is to contain the certain league MVP, Cam Newton, and the only team in the league to score 500 points, Phillips has to pitch the kind of perfect game Belichick threw at the Buffalo Bills 25 years ago, back when a lot of football people thought the Bill Parcells aide was born to be a career coordinator, too."
