Let's start here -- no driver deserves to get flipped in the air and risk death. Nobody's advocating that, nobody wants that.

But Brad Keselowski can't claim that he doesn't deserve at least some measure of payback for what he's done over the last couple of years in Sprint Cup and Nationwide-level racing. He's dumped several top-level NASCAR drivers, and he's drawn criticism from many more.

Sunday's flip was terrifying, and you can see by the look on Keselowski's face above that he was deeply shaken. Thing is, could this be a case of Keselowski sowing the wind and reaping the whirlwind? Has he, by his own actions, set in motion retaliation that ended up being worse than anything he ever did? 

Let's review the video evidence, shall we?

We've all seen the videos of Carl Edwards' flip at Talladega last year. You can argue whether Keselowski was to blame; many say he wasn't, and there's evidence to support that. But last fall at the same track, Keselowski apparently contributed to a Big One that torpedoed the Cup chances of Mark Martin and Jeff Gordon:

But it was the Nationwide Series where Keselowski has had the most, shall we say, "incidents." Here's the dustup between Edwards and Keselowski in Memphis last year that may have precipitated Sunday's wreck:

Also last fall, Keselowski got into longtime rival Denny Hamlin in Dover:

After the Dover incident, Hamlin and Keselowski had this to say on their feud:

Two weeks later in Fontana, Keselowski tangled with Justin Allgaier:

Later in the race, Keselowski got into it with Hamlin and Greg Biffle:

And in Phoenix a few weeks later, Hamlin and Keselowski once again crossed paths:

Check out these reactions from Phoenix, particularly Jason Ratcliff, Kyle Busch's crew chief, who said, "Somebody's going to get angry and [retaliate] at a higher-speed racetrack." 

Finally, in Homestead, Hamlin gave a clinic on how to spin somebody:

And looking back, here's where it all began, as Keselowski, Hamlin and Dale Earnhardt Jr. got into a fight that spilled over into their crews.

So there you have it. Many drivers have knocked Keselowski for being immature and reckless. Perhaps after this, everybody will think a little more about their actions. And perhaps not.
