There was a breakdown. An opening season collapse for the Broncos seemed to too closely like that of the Super Bowl itself, and Madden 23 coins at that point, the team was never as good as they believed they could take home the trophy. Following a close loss to the poor 49ers (who finished 2-14 that season) the collapse was underway. The Panthers were beaten four times in a row, Newton was mistake prone and each week Carolina looked like it was trying to get itself out of the deeper and deeper hole.
Let's presume for a moment that the problem for the team was psychological. It's unclear what the record would be. Even a Super Bowl win could have resulted in a hangover but at a minimum the Panthers would have played more confidently. This is crucial to the year ahead and beyond.
Consistent inconsistency has been the mantra for the Panthers for as long as the franchise has existed. A seemingly endless rubber banding of sky-highs and brutal lows with nothing in between. If you had won that Super Bowl, finally getting over the hurdle, could have been a major change.
General director Dave Gettleman would have stayed as a player in the year 2017. It's a fact that the Super Bowl would have assured this, which dramatically alters the Giants' history too. Without Gettleman it's likely that the team chooses Saquon Barkley, instead likely opting for Sam Darnold -- which ensures that the Jets' QB within the same city and in different colors.
After Gettleman's departure the Panthers began to look like a team running over time. Ron Rivera seat was getting hot, Newton was struggling, not only on the field but also with injury. Everyone in the arena felt they had to win immediately. If Carolina had won Super Bowl 50 they would have a mammoth hanging point to put their caps on. Newton, as an NFL-winning quarterback and the previous MVP likely would have laid off his injuries that were getting worse, similarly the team wouldn't feel that they were in a position to return him quickly -- increasing the severity of the problem.
There's a high probability of winning the Super Bowl would have led to Newton remaining his quarterback for the Carolina Panthers, Dave Gettleman still being the GM, in addition to Ron Rivera remaining head coach. These ripples would have spread across the league and cheap madden 23 coins affected dozens of franchises.
