Former NASCAR Cup Champion Kyle Busch dead at 41

[Max Rockatansky]

Apparently Kyle Busch was hospitalized with some sort of illness this morning.  News sources and NASCAR are running now that he passed away.

This is one of the worst days in NASCAR history. RIP to my favorite driver and one of the greatest ever.

I am just devastated.

Funny, what different worlds we all live in.

I mentioned the news to my wife, and she replied, —Never heard of him.

I'd heard of him, but knew nothing about him beyond his being a NASCAR driver.

So heartbroken right now for Samantha, Brexton, Lennix, Kurt and Richard. Right now I'm so shaken that I almost don't want to watch NASCAR for a while, but after the initial shock wears off I know I'll be tuning on on Sunday for Kyle.

He was one of the best post-Dale Earnhardt NASCAR drivers and won two championships at the Cup (formerly Winston Cup) level.  Historically he is mostly associated with the 18 M&Ms car from Joe Gibbs racing.  In recent years he's been racing for Richard Childress in the 8 car.

A healthy 41 year old going from driving on Sunday to dead on Thursday is very strange. My medical professional wife is trying to figure out what it might have been.

Yeah, just terrible.  There have been enough cases like this in sports (and entertainment) that you tend to jump to a substance abuse conclusion, but that would not appear to be justified here.

Busch appeared to be ill two weeks ago at Watkins Glen, when he radioed his team during the race and asked for Bill Heisel, a veteran sports physician assistant who has worked with NASCAR drivers and crew members for years, to meet him at Busch's motorhome after the checkered flag.

"I'm gonna need a shot," Busch told his team then.

Asked by The Athletic last week about whether he was feeling better following that radio message, Busch waved his hand to motion toward his face.

"You can kind of hear it — I'm still not great," he said. "The cough was pretty substantial last week."

My wife was somewhat surprised that the Carolina Hurricanes had a moment of silence for him before last night's game. I then explained that when I went to a Carolina Panthers NFL game in Charlotte, in addition to football scores the out-of-town scoreboard showed the running order for that Sunday's Winston Cup race. And when I went to a Hurricanes game in Greensboro when the team first moved down from Hartford, they had Jeff Burton do two laps around the ice in his stock car, announced as "the official Winston Cup driver of your Carolina Hurricanes." I guess if you haven't lived in the Carolinas you don't necessarily get a sense for how ingrained NASCAR is down there.

The rumor mill is working overtime about his cause of death, although I hadn't heard substance abuse yet.

I was not a Kyle Busch fan. In fact, I despised him on a level reserved for Bubba Wallace and Denny Hamlin. I much preferred his brother Kurt. But I recognized his talent and it's hard to believe how quickly things can happen.

I think it highly unlikely that a person with a substance abuse problem could compete at the highest level of motor racing. I'd be shocked if that was the cause.

There has been a couple notable Cup drivers with substance abuse issues over the recent decades.  Not that I'm saying Kyle Busch is one of them.

RCR has announced that #33 will replace #8 on the car for at least the rest of the season. RCR's NOAPS series driver Austin Hill will drive the car this weekend. No announcement yet on who will drive it the rest of the season.

Just saw a post from Bob Pockrass on what caused the death of Kyle Busch. "The medical evaluation provided to the Busch Family concluded that severe pneumonia progressed into sepsis, resulting in rapid and overwhelming associated complications."

[Max Rockatansky]

That's pretty shocking to see an athlete get taken out by that.  That's what got my grandpa on my mom's side.

I know that NASCAR drivers aren't NBA-level athletes, but staying in driving shape is much more rigorous than it was in, let's say, the Tony Stewart days. If he had pneumonia and decided to work through it instead of taking a week off and treating it, it's  not shocking at all that it turned into sepsis.

Recently Kevin Harvick had a podcast segment during which he talked about how many calories he was expending during a Cup race.  Apparently his heart rate was around 140 BPM and he was burning about 3,500 calories on average during Cup races.  Those aren't dissimilar numbers to what I pull on Marathon running distances. 

Tony Stewart probably the last notable driver that was competitive and not in very good shape.  Even still, put him next to Jimmy Spencer or J.D. McDuffie from a racing generation prior and he would look tiny.  I'm not sure how drivers like that could hack the physical exertion of being in a race car for three to four hours. 

Interestingly, I recall Mr. Marcis being a deceptively strong person.  He is not a large man and I never saw him exercise once in all the years I've known him.  Even still he usually came out of the car after races like it was no big deal and lugged heavy equipment to the hauler.

The only reason I mentioned substance abuse was to shoot it down, because there was immediate evidence that he had been sick, the specific illness just not being clear until today.

It's just that there have been quite a few athletes, actors, musicians etc. who died suddenly at a very young age, and drugs have been the cause so often.  And in many cases they were performing at a top level a few days before they died.  I think of somebody like Tyler Skaggs, the pitcher for the Los Angeles Angels, who pitched a game on June 29, 2019 and then was found dead in his hotel room on July 1.  He had mixed alcohol, fentanyl and oxycodone, with the drugs being supplied by an Angels staff member who is now doing 20 years for his responsibility in Skaggs' death.

That whole Jeremy Mayfield thing was BS, in my opinion.

Mayfield was no angel.  Once he began winning at the Cup level he dumped his original wife fast and married a model.  There wasn't a lot of kind words about the guy in the garage leading up to him signing with Penske.  His recent social media posts strike me as an unstable personality (either influenced by drugs or not).

The lead up to Tim Richmond resigning from Hendrick IMO was quite the controversy.  Rumor was that the France family wanted him gone amid the HIV rumors and rigged a drug screen.  I want to say he actually passed a second test?

Former Cup Rookie of the Year Rob Moroso was killed when he wrecked on a public road while drunk.  He was apparently known for reckless behavior on public roads.

[hbelkins]

Mayfield, being from Kentucky, was one of my favorites. He lost some favor with me when he dumped his fuller-figured wife for the slimmed-down version.

With Kyle Busch's cause of death reportedly being severe pneumonia that turned into sepsis the cause raises some big questions. Professional race car drivers have access to some better than average doctors and medical care. How did those doctors miss this? Or did Kyle Busch blow off the symptoms he was experiencing and refuse to let doctors examine him? How hard could it have been to just get a chest x-ray and/or do some blood work?

Pneumonia is nothing to mess around with. People don't just get over it like some ordinary bug. About 20 years ago I wound up with pneumonia after trying to self-medicate my way through a stubborn case of bronchitis that had been going on for more than two weeks. What made me finally go to the doctor was a coughing fit where each cough caused a hard, almost stabbing like pain in the back of my rib cage. The doctor took a chest x-ray. He could see one of my lungs was mostly full of infectious gunk. He said if I procrastinated just one more day I would have had to be hospitalized. I was in my late 30's then -almost Kyle Busch's age when he died. Funny thing: the shot of penicillin in the butt cheek, the Zythromax™ antibiotics and steroid z-pack he gave me had me feeling so much better just a day or two later.

I wish Kyle Busch had just gone through a bit of inconvenience to let the doctors really see what the hell was going on with him. If they could have diagnosed this stuff early Busch probably would have been back to 100% really quick and not miss any racing time.

[Max Rockatansky]

Most drivers will do anything they can not to miss a race due to injury, illness or other reasons.  Missing races has historically had huge negative points consequences during most of the history of NASCAR. 

One of Kyle Busch's Chase-era championships (2015) actually came during a year during which he missed a bunch of races (due to an injury) when a race win with a waiver got you in.  The current points format doesn't allow for a similar scenario to happen.
