The 2015 NASCAR season was quite eventful — but most of the news happened off the track. So while the on-track product didn’t provide much to talk about (the low-downforce package can’t get here soon enough), there were still plenty of headlines.

Now that the season has been over for a couple weeks and the hangovers from awards weekend in Las Vegas have subsided, here’s the top 10 stories of the year in order of magnitude:

10. Charter system gets closer

If this comes to fruition, it’ll be one of the top stories on the 2016 list. But for now, the proposed charter system for race teams is still in the discussion stage.

Should it happen, the franchise-type format will be a game-changer for team owners. They will have more financial stability and more say in what happens with the sport. But it could make it harder for new teams to enter the Sprint Cup Series.

9. Daytona 500 qualifying fiasco

Knockout qualifying has been a great improvement to NASCAR’s race weekends in the past two years, with a notable exception: It didn’t work at restrictor-plate tracks.

Officials kept trying different ways to make it happen, but it was like putting a square tire on a round wheel. That was no more apparent than during qualifying for this year’s Daytona 500, which left some drivers wrecked and fuming (it did result in an epic Clint Bowyer rant, however).

Fortunately, NASCAR implemented a hybrid old/new qualifying style for restrictor-plate tracks in time for the May race at Talladega Superspeedway.

8. Confederate flag controversy

NASCAR waded into the debate over the Confederate flag after South Carolina removed it from the grounds of the state capitol following the Charleston shooting in June. Brian France denounced the flag as “offensive and divisive” and tracks encouraged fans not to display it at racetracks.

However, the move seemed to backfire among fans. The number of visible flags in the infield campgrounds ballooned in an act of defiance following NASCAR’s statement.

Instead of just criticizing it, NASCAR could have completely banned the flag from track property if the sanctioning body wanted to make a real impact. But that might have hurt the tracks in the wallet, so there was no real change.

7. Rules packages

This was a new one: In an attempt to find a better aerodynamic racing package for next season — an acknowledgment the current one wasn’t good enough — NASCAR experimented with two different packages over four races this season.

The low downforce package, preferred by the drivers, put on fantastic shows at Kentucky Speedway and Darlington Raceway. Seriously, it was great. Everyone was pumped. Meanwhile, NASCAR’s preferred high-drag package totally flopped at Indianapolis Motor Speedway and Michigan International Speedway.

Thankfully, low downforce won out and became the standard for all races (except restrictor-plate events) starting next season.

6. Drivers council formed

Instead of speaking with individual voices, drivers were given the opportunity to present their viewpoints to NASCAR for the first time with a formally elected drivers council. The first meeting of the peer-voted group was in May at Dover International Speedway, and several more meetings with top brass were held throughout the year.

This was a huge win for everyone in the sport. Tony Stewart called it one of the greatest things he’s experienced in his career. NASCAR, once a dictatorship, had been listening much more often through meetings with owners and manufacturers; now the drivers have a true platform to get their opinions transformed into policy.

5. Tony Stewart announces retirement

Though it will be a bigger story in 2016, the official announcement that next season will be Stewart’s last is significant. NASCAR is losing a three-time champion and a major personality with a large fan base, and that will hurt.

Clint Bowyer will step into Stewart’s No. 14 car in 2017, and Stewart will still be around through his role as co-owner of Stewart-Haas Racing. That’s good, because NASCAR is more interesting when “Smoke” is involved.

4. Matt Kenseth suspended two races for wrecking Joey Logano

Kenseth’s blatant wreck of Logano at Martinsville Speedway — retaliation for an earlier incident at Kansas Speedway — divided NASCAR like few other issues in recent years. And when NASCAR suspended him for an unprecedented two races? It was explosive, to say the least.

Opinions were heated on both sides. Some felt Kenseth was justified, some thought he dramatically crossed the line and many were upset with NASCAR for what they viewed as an inconsistent punishment.

Kenseth returned for the season finale at Homestead-Miami Speedway and met with Logano beforehand, but the frostiness between the two will likely linger; neither spoke to the other during the recent Champions Week in Las Vegas.

3. Kurt Busch domestic violence suspension

Few stories these days make headlines outside of NASCAR, but this one certainly did. Thanks in part to wild accusations on both sides of the alleged domestic violence incident between Busch and ex-girlfriend Patricia Driscoll (who Busch said presented herself as a trained assassin during their relationship), this case played out very publicly.

It was also at the height of a national conversation about domestic violence that started with incidents in the NFL. So when a Delaware family court commissioner ruled Busch probably committed the act, NASCAR did the only thing it could: It suspended him for the Daytona 500 and beyond.

But when no charges were filed against Busch, NASCAR did the right thing again and reinstated him after three races. Busch then rallied to make the Chase, had a fantastic season and put the past behind him. He announced in August he was engaged to Ashley Van Metre.

2. Jeff Gordon retires

Many people will argue this should be the top story of the year, and there’s certainly a case to be made for that. Either way, Gordon’s retirement was a season-long topic that only got more discussion as he kept advancing during the Chase — even winning his final career race at Martinsville along the way.

This wasn’t just any future Hall of Fame driver retiring — even though the four-time champion’s stats are legendary in themselves. No, this was about Gordon’s impact on stock car racing and how he helped transform NASCAR from a regional sport to a national one.

He’ll still have a weekly TV presence for the first half of next season through his role as a Fox Sports analyst, but that’s small consolation for fans who now have to find a new driver to root for.

1. Kyle Busch’s remarkable comeback

Gordon’s retirement would have been No. 1 in almost any other year, but nothing can beat Kyle Busch’s storybook season.

The word “unbelievable” gets thrown around a lot, but this truly was beyond belief. Busch broke his right leg and left foot in a crash the day before the Daytona 500, and there were many questions in the aftermath. Would he race again? If so, when? Would he be the same?

But he came back way ahead of schedule (after learning how to walk again!), somehow won a race, then three more in a row, then improbably made the top 30 in points.

All of that would have been enough to make for an incredible story, except there was more. He advanced through the rounds of the Chase and won the final race of the season to clinch his first career title in the most difficult year of his life.

How do you top that? You can’t. And that’s the No. 1 story of 2015.

Steve Byrnes dies: The death of the Fox Sports broadcaster deeply affected the NASCAR community and was certainly one of the most significant stories of the year.

Byrnes’ fight against cancer was inspiring, and his positive attitude through the battle was something many of us will never forget. He will truly be missed, which was evident by the amount of support displayed by everyone in NASCAR. The spring Bristol race was named in his honor.

Other big stories: Controversy at the end of the Talladega Chase race, Austin Dillon’s Daytona crash in which five fans were hurt, souvenir haulers getting replaced with a merchandise tent, tire tampering rumors eventually leading to Ryan Newman’s penalty, GoDaddy leaving NASCAR/Danica Patrick and the No. 44 car being stolen from a hotel parking lot near Atlanta.
