The so-called “Kardashian Curse” is a well-documented urban legend. It goes something like this: A male athlete becomes romantically involved with a member of the Kardashian-Jenner crew, and all of a sudden, things start going wrong for him. People have also applied the curse to other celebrity Kardashian relationships as well, arguing, for example, that Kim is the reason Kanye West has been going crazy over the past five years, while ignoring that he’s been kind of nuts his whole career. But have the sisters actually ruined the careers of athletes? Let’s find out.

Reggie Bush

Let me just say this first: Reggie Bush was one of the greatest running backs in college football history, and it’s an absolute travesty that he was stripped of his Heisman trophy. With that out of the way, Reggie Bush famously dated Kim Kardashian from 2007 to 2009, encompassing Bush’s second through fourth seasons in the NFL. If you’re arguing for the curse, you could point to the fact that Bush had almost 400 yards less from scrimmage the year he started dating Kim. However, he had his most efficient season in 2009—a year in which he and Kim split and then got back together—with 5.6 yards per carry. And he also won the Super Bowl while they were dating.

The Verdict: No Curse

Lamar Odom

This is the most serious (and sad) instance of the curse. Odom married Khloe in 2009, just as he was approaching the apex of his NBA career. While he was not quite the dominant scorer he’d been when he entered the league in the early 2000s, Odom was a valuable role player for the Los Angeles Lakers, and his marriage to Khloe was exactly in the middle of the two consecutive championships he won in LA. He also won NBA Sixth Man the next year—but things unraveled from there. The stress of starring in his very own Kardashian spin-off (and generally living the celebrity lifestyle) weighed too heavy on Odom, whose life began to spiral post-2013. It’s not necessarily Khloe’s fault that Odom’s life went the way it did, but it certainly seems like his life was ripped apart by the Kardashian whirlwind.

The Verdict: Curse

Tristan Thompson

Thompson, the former fourth overall NBA draft pick, began dating Khloe Kardashian in the summer of 2016. They apparently debuted as a couple at Flo Rida’s birthday party (this is pretty neat). Anyway, Thompson was a key player in the Cleveland Cavaliers’ 2016 title run, and statistically, he kept up that performance even after getting involved with Khloe. This season, however, he has been pretty bad—averaging just 2.1 offensive rebounds per game, which isn’t that good for a player whose primary skill is supposedly his offensive rebounding. Is this due to his relationship with the now-pregnant Khloe or simply due to the general 2017 Cavs disfunction? There’s no way to know for sure.

The Verdict: Unclear

Kris Humphries

Kris Humphries also dated Kim Kardashian and was married to her in a definitely-completely-real-and-not-a-publicity-stunt way for a grand total of 72 days. All in all, their entire relationship lasted just a little past the 2010-2011 NBA season. Humphries, defying the apparent witchcraft that comes with dating a Kardashian, had a great year while they were together, averaging 10 points and 10.4 rebounds—the second best statistical season of his career.

The Verdict: No Curse

Blake Griffin

Griffin is an NBA superstar and was a borderline MVP candidate a few years ago. He’s also an aspiring stand-up comedian. He is also in a casual, on-again-off-again relationship with Kendall Jenner. Did Griffin’s relationship with Jenner cause his recent trade to the Detroit Pistons, a major blow to his celebrity ambitions? Will Jenner break up with Griffin because he is no longer living in Hollywood? How do we interpret Jenner wearing a Pistons hoodie on her Snapchat? It’s too early to tell, but whatever happens next in Griffin’s career will (probably) be Jenner’s fault.

The Verdict: Still Undecided

Jordan Clarkson

Like Griffin, Jordan Clarkson is an NBA player who lived in Los Angeles, was for a time dating Kendall Jenner and was recently traded to the frigid Midwest. However, Clarkson was traded to the Cavaliers, meaning he went from playing with Julius Randle to playing with Lebron James—a pretty clear career upgrade. If dating Jenner really does cause trades, this one seems to have worked out pretty well for Clarkson, who will now more than likely play for an NBA title in June.

The Verdict: No Curse
