As much as heat, humidity and playbooks, a Super Bowl guarantee is an essential part of nearly every NFL training camp.
The Carolina Panthers have usually had at least one player boldly proclaim the team will end up in the Super Bowl -- which has happened in reality only once in 20 seasons.
This year's first proclamation was issued Thursday morning on move-in day by defensive end Mario Addison, who said to a group of us reporters: "We're going all the way, man. We've got all the tools. All we've got to do is put it together, and I see a Super Bowl. I feel it."
Was that a Super Bowl guarantee?
Never miss a local story.
"We're going to the Super Bowl," Addison repeated. "I can feel it. If you speak on it, man, it'll happen."
The most famous Carolina Super Bowl guarantee came from Pro Bowl center Ryan Kalil. He took out a full-page ad in The Charlotte Observer in July 2012 to predict the Panthers would win the Super Bowl that season (they finished 7-9).
What Kalil did, though, was different only in the fact that he bought the ad. "Every team says it every year, whether it's publicly or not," Kalil told The Observer back in 2012. "They say they're going to win the Super Bowl."
Addison, who said he based his prediction on the idea that the Panthers had "better everything," had a career-high 6.5 sacks in 2014. He did that for a Carolina team that for the second year in a row won the NFC South and advanced to the NFL's final eight before getting knocked out of the playoffs.
