How much would Kyle Busch’s excoriation of the racing Monday at Dover International Speedway draw the ire of NASCAR?

Discussions took place Tuesday (as part of the sanctioning body’s weekly postrace analysis) on whether to punish the 2015 series champion. Late Tuesday afternoon, a NASCAR spokesman said Busch wouldn’t be fined.

It was an interesting window into the new dynamics of NASCAR leadership and the sanctity of a rules package that has been a central storyline of the 2019 season.

By previous standards, Busch’s harsh assessment of how higher speeds impacted the racing at Dover might have crossed NASCAR’s boundaries for language detrimental to stock-car racing.

Series officials previously have said drivers are welcome to criticize them for their calls but draw the line on assailing the entertainment value of the on-track product. In announcing the abolition of its “secret fine” policy, Brian France said sanctions publicly would be levied on those perceived as denigrating NASCAR, and it’s been applied (sometimes capriciously) to Ryan Newman, Denny Hamlin and Tony Stewart for their views on restrictor plates, the Gen 6 car and loose wheels.

However, Busch’s comments weren’t completely out of line given NASCAR’s expectations for a radically different rules package in 2019.

During a critical preseason test at Las Vegas Motor Speedway, vice president of development and innovation John Probst told JeffGluck.com and other reporters that NASCAR “wanted cars close together. We don’t want people falling off and going laps down. We don’t want people checking out.”

Martin Truex Jr. won Monday’s rain-delayed race at Dover by 9.5 seconds, a margin of victory greater than the previous 10 races combined this season, and even Truex said passing was difficult for his No. 19 Toyota.

It’s also worth noting that Probst said during the Las Vegas test that most drivers were opposed to the new rules – and many seem to have been biting their tongues when asked to evaluate the rules. The introduction of 550 horsepower at larger speedways was intended to keep cars closer together, but the reviews have been mixed.

Though Kevin Harvick offered a stronger opinion Monday after Dover, his restraint after a March 23 qualifying session at Martinsville Speedway reflected the reticence many drivers have had about the package this season.

“Look, I bailed on having an opinion on rules and downforce the middle of last year,” Harvick said, apparently referring to when NASCAR moved in the direction of the 2019 rules after a version was used in the All-Star Race.

Martinsville was among the 2019 races in which drivers were more vociferous about the impact of the rules on passing.

Those complaints have undoubtedly been heard by Jim France, who took over as NASCAR CEO for his nephew, Brian, nine months ago and has been a much more visible presence and sounding board at the racetrack.

Though his leadership style has been universally praised for its connectivity, Jim France also has an old-school approach that is in line with his late older brother who ran NASCAR for more than 40 years.

Traditional hard-line leadership at NASCAR has been less receptive to rebukes from drivers, and a punishment for speaking out against the 2019 rules – which likely will remain for the foreseeable future – might have sent the message that some sacred cows remain in Cup.

Perhaps more at risk for NASCAR sanction was Leavine Family Racing owner Bob Leavine, who began tweeting his support of Busch and his dissatisfaction with the rules since shortly after Monday’s race ended in a tweetstorm that lasted more than a day.

“It’s unfortunate, especially when a team owner does social media,” NASCAR senior vice president Steve O’Donnell told SiriusXM’s NASCAR channel Tuesday morning. “I don’t think that’s the right way to do it at all. It’s a choice that was made. We’re available every race and talk to every constituent we have. Jim France is at every race, which is phenomenal. The ability to say that you don’t have a chance to talk to us about your feedback is a bit questionable.”

NASCAR ultimately declined to punish Leavine, too.

The team owner has some leverage. As he noted, he is a Race Team Alliance board member. He also has a midpack team that joined the Toyota Racing Development fold this season.

With open speculation about Toyota’s desire and need to add another car to its lineup, an expansion of LFR would be the easiest option. If Leavine were to leave NASCAR (and this tweet didn’t exactly inspire confidence about his long-term belief in the product), it would leave a gaping hole that would take a lot of effort and money to fill.

Prior to Martin Truex Jr.’s wins at Dover (1-mile track) and Richmond Raceway (the 0.75-mile layout where he scored his first short-track win in Cup), his previous 12 wins had come at ovals either 1.5 miles and longer or road courses.

Because his 2017 championship was built on the 1.5-mile tracks (a record seven wins, including the championship finale at Homestead-Miami Speedway), it’s easy to overlook Truex’s versatility. His 0-for-80 winless stretch on short tracks was an anomaly, and his team’s only weakness is on superspeedways, which are largely immaterial to winning a title once a driver has qualified for the playoffs.

With two wins in three races, Truex and crew chief Cole Pearn seem fully assimilated into Joe Gibbs Racing and poised to continue a five-season run as a first-tier championship-caliber duo.

Truex’s win also helped make a strong case for cementing JGR as the reigning top team in NASCAR’s premier series. Between Busch, Truex and Denny Hamlin, Toyota is the only manufacturer with a trio of multiple winners, and Erik Jones has shown signs of righting the ship in the past two races.

Team Penske might remain a clear second in the pecking order, but there weren’t many highlights at Dover with Joey Logano (who fought for a sixth after getting mired deep in traffic from playing two-tire strategy to win a stage), Brad Keselowski (who faded greatly to 12^th after leading 58 of the first 181 laps) and Ryan Blaney (15^th).

Those struggles, coupled with Hendrick Motorsports’ four top 15s, underscored that the battle behind Gibbs has been tightening.

The tactics of Logano and William Byron revealed how strategy can be tricky with races that run largely incident-free. Both drivers sacrificed track position for Stage 1 points and then spent much of the remaining 280 miles trying to regain ground.

Dover marked the sixth of 11 races in 2019 that didn’t feature a multicar wreck, and the resultant lack of yellows can make it difficult to catch a tactical break. Logano and Byron both abandoned long-run strategies to short pit and get on sequence with the other lead-lap cars for their final stops with around 80 laps to go.

Gambles on being able to stay out longer under the final green-flag run (which lasted 131 laps) went unrewarded for Daniel Suarez, Jimmie Johnson and Aric Almirola, who would have benefited if there’d been a late caution.

The return of single-car qualifying at Dover was kindest to the less experienced. Four of the top five qualifiers (Chase Elliott, Byron, Kyle Larson and Alex Bowman) weren’t running Cup full time in 2013, the last season before the debut of group qualifying.

With only one driver starting in the top 10, qualifying at Dover was surprisingly unkind to JGR. During the 2013 season, JGR had three of the top four qualifiers (Matt Kenseth, Busch and Hamlin), and Truex also ranked in the top 10.

The demise of Furniture Row Racing sadly cut short one of NASCAR’s great underdog stories, but it’s good to see at least one thread remains to the Denver-based team.

Though only a handful of several dozen team members at Barney Visser’s defunct organization migrated with Truex to the No. 19 Toyota, Pearn keeping his postrace victory selfies tradition alive is a welcome reminder of the iconoclastic camaraderie that powered Furniture Row (even if the beards are gone).
