Peyton Manning's last game? Cam Newton's finest moment?
For all the golden tinge the NFL is placing on Super Bowl 50, this one just might come down to how the two star quarterbacks deal with the dynamic defenses bent on humbling them.
There can't be a better storyline than a five-time MVP likely to take his final snaps with a championship on the line. Except, perhaps, the league's rising star carrying his franchise to its first NFL title in the face of detractors.
Senator Bernie Sanders defended himself Sunday against criticism that he does not have sufficient depth or interest in foreign policy matters.
"Let me reassure the American people…it goes without saying that a president must be well-versed in foreign policy, must have a foreign policy position. And I will of course do that," Sanders said on NBC's "Meet the Press" in response to criticism by some of his debate performance Thursday on the issue of foreign policy.
Sanders has faced intense scrutiny during his presidential campaign for not being as comfortable or fluent as former Secretary of State Hillary Clinton when discussing foreign affairs.
"It is not just experience that matters, it is judgment," argued the Vermont senator.

Donald Trump was back, Carly Fiorina was out and Sen. Marco Rubio of Florida was drawing attacks after his strong showing in Iowa. The GOP presidential candidates were on stage Saturday night for the final debate before the New Hampshire primary, where some of the Republicans must do well if they are to continue. Trump, who finished second behind Sen. Ted Cruz of Texas in the Iowa caucuses, returned after skipping the last debate. Fiorina, the former CEO of Hewlett-Packard, was excluded by the rules of host ABC News. Here are some of the liveliest moments of the evening.
Twitter CEO Jack Dorsey said the social media website's stream of tweets will stay live and in real time, disputing a media report that a change was in the works.
News and entertainment site BuzzFeed reported on Friday that Twitter was going to introduce a timeline based on an algorithm rather than a real-time stream. The report upset some users, who created the hashtag #RIPTwitter to debate the change.
But Dorsey took to Twitter on Saturday to dispute the report.
"Twitter is live," he tweeted. "Twitter is real-time."

With much of the NFL world camped out in the San Francisco Bay Area in the days before Super Bowl 50, researchers released sobering news: late Oakland Raiders quarterback Ken Stabler had a degenerative brain disease associated with repeated blows to the head.
Dozens of former players have been diagnosed with chronic traumatic encephalopathy, some who died in old age, like Frank Gifford, and a few who took their lives, like Junior Seau. There is no known treatment, or even a test that can point it out in the living - it's detected in post-mortem brain scans. But to one former player who's sure his nine-year career gave him the disease, there's an obvious treatment that isn't allowed in the NFL, yet will be easy to score right near Levi's Stadium during the Super Bowl this Sunday for anyone with a doctor's note: medical marijuana.
South Korea said it has agreed to begin talks with Washington on the possible deployment of a U.S. missile defense system, hours after North Korea launched a rocket in defiance of international warnings, NBC News reported.
Meanwhile, the United States, Japan and South Korea have requested an emergency meeting of the United Nations Security Council Sunday to discuss the launch.
The South Korea-United States discussions will examine the possibility of deploying the Terminal High Altitude Area Defense system on South Korean soil, South Korean deputy minister for policy Yoo Jeh-seung said at a joint briefing with U.S. Army Lt. Gen. Thomas Vandal.
"Both governments have decided that North Korea's recent nuclear experiment and firing of long-range ballistic missile are a serious threat to the peace and stability of the Asia-Pacific region," a South Korean military officer told NBC News.
The announcement comes after North Korea launched a rocket carrying what it claimed was a satellite into orbit Sunday morning, a month after the isolated country claimed to have conducted a hydrogen bomb test. The United States and Japan condemned the launch as a thinly-veiled test of ballistic missile technology, and a provocation.

Baltimore City Police said an altercation at a Fells Point bar caused a driver to crash into several vehicles before running down a woman in an out of control scene caught on camera.
Police said Orlando Redd, 28, of Parkville, was assaulted inside a bar on South Broadway around 2:15 a.m. Saturday. After fleeing the bar, Reed got into his minivan where the assault continued.

A bus has exploded in central London — but this time it's only for a movie.
City officials Sunday reassured the public that the explosion was a movie stunt for "The Foreigner" starring Jackie Chan and Pierce Brosnan.
The sight of the bus in flames and the twisted wreckage afterward caused consternation on Twitter from London residents who said the public had not been adequately warned about the stunt. Some complained that children had been frightened by the blast.
It reminded some of the 2005 attack on London's transport system that killed 52 civilians. That attack included the explosion of a bus in central London.
Donald Trump said Sunday that he does not need to win the New Hampshire primary and that the Iowa caucus results were "very unfair" to him and Ben Carson.
"There are those that say I actually came in first, depending on how you want to count the votes, to be honest, because that was a horrible thing that took place," Trump said on "Meet The Press."
Iowa caucus winner Ted Cruz apologized to Ben Carson after supporters spread rumors that Carson was planning to end his campaign in an effort to get them to support Cruz. Trump has said it may have pushed Cruz over the top and caused him to fall to second.
Trump said he would like to do well in the Granite State, but dismissed the idea it is a must win.

Two teen brothers are dead and six others injured following a late-night accident on the bobsled track at the Canada Olympic Park in Calgary, NBC News reported.
Twin brothers Jordan and Evan Caldwell, 17, died at the scene after a group of teens broke into the facility and used a "personal sled" on the bobsled track early Saturday morning, police said.
"Part way down, the group hit a large gate used to separate the bobsled and luge tracks," police said in a statement.
The other six teenagers were taken to hospital with injuries ranging from minor to serious, police said in a statement, adding that the nature of their injuries made it difficult to identify "many" of the victims.
Police said CCTV footage was being reviewed and investigators were working to determine how the teens entered the facility, which hosted events at the 1988 Winter Olympics.
