Out of every negative comes a positive, all good stems from something bad and adversity often leads to opportunity.

Or something like that.

Right?

The Bears must believe in all the psychobabble, coachspeak cliches now that their magical season disappeared Sunday night when Cody Parkey’s 43-yard field-goal attempt hit the left upright and caromed off the crossbar in a soul-crushing 16-15 playoff loss to the Eagles. “CLANKS FOR THE MEMORY!” Monday’s edition of the Philadelphia Daily News screamed. One day, Bears fans might chuckle at the headline — but likely not one day soon.

The pain was palpable as thousands of stunned people fled Soldier Field after Parkey’s miss, a Bartmanesque reaction combining regret, sadness and anger. It instantly became one of Chicago’s classic sporting moments nobody in town ever will forget, hard as they may try. It was mesmerizing to watch and challenging to describe how Parkey hit an upright for the sixth time this season with so much at stake. Imagine how it felt to experience it.

That feeling figures to haunt the Bears every day of the offseason, agony that often precedes ecstasy in sports. The Bears have been to the Super Bowl twice — after the 1985 and 2006 seasons. Both NFC champions were fueled by painful playoff exits the previous year.

On Jan. 6, 1985, the 49ers shut out the Bears 23-0 in the NFC championship game in San Francisco, a lopsided embarrassment that served as motivation for one of the all-time great Super Bowl runs. On Jan. 15, 2006, a Panthers team coached by John Fox eliminated the Bears 29-21 at Soldier Field in a divisional playoff game wide receiver Steve Smith dominated badly enough to frame the context for the following season. The deepest playoff scars never go away.

That came to mind Sunday night as coach Matt Nagy tried putting the Bears season into perspective within minutes of it ending abruptly, the emotion making his eyes moist and his voice strained. Nagy likened the long faces he saw while addressing players in the locker room to their dejection after the Week 1 loss to the Packers that preceded a special season almost nobody outside of Halas Hall saw coming.

Photos of every Bears touchdown scored during the 2018 season.

“I’m going to hurt right now for a little bit,” Nagy said. “I’m going to feel it, as everybody should, but it’s going to make me better.”

The same goes for every member of the organization, from the front office to Nagy and his coaching staff to the 53rd man on the roster. Sunday’s setback eventually will make everyone better. The Bears just scratched complacency from their 2019 schedule. One of the surest ways to sustain success is to deal with failure, and the anguish all over the faces of Bears players after Parkey’s miss steeled a team that will report to Bourbonnais in July with high expectations.

For the good of everybody, the Bears should make sure Parkey isn’t among those reporting. Players publicly supported Parkey, and Nagy vowed to “do everything I can to take a part of the human side,” but honestly, both sides might benefit from a change of scenery. To fans with long memories, Parkey always will represent a symbol of disappointment. To 52 teammates, he is the guy who missed 11 kicks and forced them to answer countless questions. To Nagy, he is a liability the coach no longer can trust.

In a bottom-line, results-oriented business like the NFL, the solution seems simple: Release Parkey once the dust settles next month.

Focusing on the fact Eagles defensive tackle Treyvon Hester tipped Parkey’s kick and the NFL officially recognized it as a blocked field goal ignores its low trajectory. Worrying whether the salary-cap-strapped Bears can afford to cut a kicker guaranteed $3.5 million next year overlooks the bigger question of whether they can afford not to. The Bears likely will address roster concerns at right tackle, running back and the secondary, but none looms as large as kicker, the team’s most glaring weakness exploited in the season’s biggest game.

Beyond their Parkey problem, the Bears can find comfort in continuity. The core of the NFL’s stingiest defense returns under contract. Even if defensive coordinator Vic Fangio leaves for a head-coaching job, enough talent exists to ease the transition for any successor. The offense will benefit from players immersing themselves into Nagy’s scheme for an entire offseason.

The way the season ended was disappointing, but that doesn’t make the season a disappointment. It’s a subtle but significant distinction that must be made as a city revitalized by the Bears anticipates what’s next. Under a first-year coach with a 24-year-old quarterback starting his first full season, the Bears won 12 games. They suffered five losses — two by one point, two by a field goal and one by a touchdown. They were competitive in every game. They were one of the most compelling teams in the league. They were relevant again, and as difficult as Sunday’s ending was for everyone to process, it confirmed a new beginning too.

That kind of hurt doesn’t exist without hope, which Chicago has rediscovered when it comes to the Bears.

“We let everybody know who we are now,” Nagy said, relating what he told his players. “I said, ‘Hey, teams are going to know, and they’re going to feel it when they walk into Soldier Field, to Chicago, and they can check that off because now they’re going to next year.’ ”

Next year can’t get here soon enough for the Bears, who lost a game Sunday but perhaps found a purpose.
