LAS VEGAS - Indianapolis Motor Speedway showed NASCAR this week what the sport's future could and should be.
Two series racing on one weekday. No practice. No qualifying. Just racing.
As NASCAR looks to make its schedule more dynamic, the idea of one-day shows for Cup has been discussed.
Those talks should go further.
Run the Xfinity Series on a weekday and the Cup Series that night in prime time.
Fans want racing. Give them back-to-back events. Don't waste time with practice or qualifying. Set the lineup based on points and go.
"I think that's the kind of open-mindedness that we need to see more of in NASCAR, honestly," Denny Hamlin told NBC Sports on Thursday of the idea. "I know that I've been in some meetings with TV partners and NASCAR trying to work on weekday races, especially during the summer. Hopefully it's on the horizon, sooner than later."
Fans saw a doubleheader Monday at Indy after rain washed out both the Xfinity and Cup races that weekend.
Such a schedule could work for one race, maybe two a season. This isn't about making the entire schedule one-day shows, but the approach would compress the schedule. That, along with limiting most tracks to one Cup event per season, could put the season finale in September instead of November.
Kevin Harvick, who has talked often about the need for bold ideas with scheduling, told NBC Sports that the key to such a one-day schedule is that "you have to protect the integrity of the racing."
But he says one-day shows could be possible.
The biggest challenge could come from track operators, who likely will raise concerns that a one-day event could reduce how many people camp and attend the event.
As NASCAR looks to race on a weeknight, limit how many days teams are at the track and alter the length of the schedule, the overriding question must be what's best for the sport. In some cases, track operators might lose out to what's best for the sport. In other cases, maybe it's the drivers or teams.
To not do anything is the wrong approach. Frankly, that's not a tactic NASCAR is taking, but words eventually need to be turned into actions.
Harvick suggests more dramatic measures.
He notes that the most talked about race this season is one that hasn't taken place yet.
The debut of Cup playoff race at the Charlotte Roval later this month has had those in the industry and elsewhere talking. Chaos, conflict and crashes are common themes from drivers, leery of the race that ends the first round of the playoffs.
"That really is something that everybody sees as unique," Harvicksaid. "We need more unique events. You need a story before the story happens."
He says more can be done with the schedule to create similar stories.
"Why shouldn't Darlington have a playoff race once in a while?" Harvick said. "Why shouldn't Bristol have a playoff race once in a while? Why is the championship race in Homestead every year? That's for us? I don't think so.
"I think it would be better to rotate (the title race) around. I think coming to Vegas for the first race of the playoffs is great. Not that Chicago was a bad spot to start it (but) starting there every year gets stale. You've got to keep it fresh."
That means new venues, date changes and other ideas. That also should include one-day shows in the summer that have the Xfinity and Cup Series race back-to-back.
"I think the way the world is today and … the ask of the fans, the expense of things, it's a valid option," seven-time Cup champion Jimmie Johnson said of the notion. "When you look back to the late '90s the way fans consumed television and their avid love of our sport and the love of the automobile, all of that, they'd want a seven-day festival for a race.
"It's just times have changed. I don't think it's a bad idea at all. Times have changed."
The 2019 schedule is set but 2020 can be a time for the sport to move forward.
2. A tiresome trend
Many drivers talked Thursday at NASCAR Playoff Media Day about needing to avoid mistakes to advance in the Cup playoffs, which begin Sunday at Las Vegas Motor Speedway (3 p.m. ET on NBCSN)
Whether NASCAR is calling tire violations more closely on pit road to set a tone or teams are trying to push things, such penalties are up dramatically the past two weeks.
NASCAR called a total of 11 penalties for tire violations the past two weeks at Indianapolis (seven such penalties) and Darlington (four).
The 11 penalties for tire violations are more than NASCAR called the previous seven races combined (10 such penalties called).
In the last nine races, Martin Truex Jr.'s pit crew has been penalized for three tire violations, more than any other team. Next is Austin Dillon's pit crew, which has been called for two such violations in that time.
3. Playoff wedding
It's one thing for drivers to be engaged during the season but married - and during the playoffs?
At least until this season.
Kyle Larson and fiancee Katelyn Sweet are scheduled to marry Sept. 26 - four days before the inaugural Cup race at the Charlotte Roval, which will determine what four drivers will be eliminated from the playoffs.
Why that date?
"Kaitlyn wants a warm wedding, and I race during the off-season so I didn't want to mess up my offseason plans," Larson said Thursday. "It happened to work out that we can do it right before the Roval there. So, it's coming fast and I am ready to get it done."
"I have kind of let her handle most of (the planning) and I will be there for the rehearsal dinner, the wedding and hopefully we don't practice on Thursday. Because that will be rough."
Cup teams will not practice that Thursday so Larson will be OK.
4. Fond memories
Rockingham Speedway, which hosted NASCAR races from 1965-2004, was recently sold and the investors want to bring racing back to the 1-mile track at some point.
Jamie McMurray, who has been hush about his future with Chip Ganassi Racing, won the final four Xfinity races there.
McMurray was recently asked about the track and recalled not those wins but a moment with his fellow drivers.
Rockingham used to hold the pit crew competition. Drivers left from the backstretch pits and come down the frontstretch pit road for their stop. While they waited for the event to begin, they hung out along the backstretch pits.
"My memory of Rockingham is sitting on the backstretch (pit wall)," McMurray said. "I was sitting back there and Mark Martin, who had won I don't know how many races at Rockingham (two Cup and 11 Xfinity races in his career). Mark is notorious for never giving himself credit and telling you how great you are. I remember Mark going: "You're the guy now, you're the man. I wish I could have done that.' Like yeah, right, this is Mark Martin.
"That's one of my favorite memories, my rookie year (in Cup) sitting back there with Jeff Burton and Mark Martin. I think Sterling (Marlin) might have been in that so there was good stories being told.''
5. Looking to keep a streak alive
Hendrick Motorsports has won at least one race on a 1.5-mile track 24 consecutive seasons. That streak is in jeopardy this year. Hendrick's only win this season came at on the road course at Watkins Glen with Chase Elliott.
Four races remain this year on 1.5-mile tracks: Las Vegas, Kansas, Texas and the season finale at Homestead-Miami Speedway.
