They won three championships together on the Lakers, but they probably could have won a few more if their egos hadn’t gotten in the way. Each accused the other of ball-hogging. Shaq said Kobe wasn’t so big, while Kobe said Shaq was way too big, calling him "fat" and "out of shape.” Kobe criticized Shaq’s leadership and his public lobbying for a contract extension. Oh, and Kobe reportedly threw Shaq under the bus when police questioned him during his sexual assault case, telling them that he should have just paid the girl off like Shaq does. While you’re stooping so low, why don’t you tell Shaq how his ass tastes?
Lewis Hamilton vs. Fernando Alonso
Alonso was Formula One racing’s reigning world champion when he joined the McLaren team in 2007, and quickly developed tension with the precocious rookie Hamilton. The two were fiercely competitive and the outspoken Alonso accused the British company of favoring its native son Hamilton and left after the season. The two have remained defiant rivals, as Hamilton went on to become the youngest F1 champion ever — unseating Alonso for the distinction.
Jason Kidd vs. Jimmy Jackson
These two, along with Jamal Mashburn, were supposed to lead the Dallas Mavericks back in the mid-90s. Instead the talented trio collapsed as Kidd and Jackson fought over the ball — and, allegedly, over the affections of singer Toni Braxton. Kidd ended up engineering a trade to Phoenix, while Jackson became a journeyman. And the Mavs didn’t “breathe again” until Dirk and Steve Nash arrived.
Ryan Newman vs. Rusty Wallace
Newman and Wallace always had a somewhat contentious relationship as Penske Racing teammates, perhaps as much because of Newman’s almost immediate success as anything else. Wallace publicly discussed what he felt was a lack of respect on Newman’s part, though he tempered his comments with comparisons to himself as a young driver. Wallace couldn’t leave it alone long after he retired from racing. When Newman announced in 2008 that he planned to leave Penske for Stewart-Haas Racing the following season in what he deemed a mutual parting, Wallace was soon quoted saying that Newman had, in fact, been fired from the team.
Matt Kenseth vs. Carl Edwards
As a couple of Midwesterners, you’d think these Roush Fenway Racing teammates could get along. But the two couldn’t be more different — the older Kenseth is vanilla while back-flipping Edwards is rocky road. Kenseth has suggested “The Carl” is bi-polar; Edwards has said that Kenseth is jealous. YouTube the video of Edwards faking a punch at his teammate after a 2007 race and judge for yourself.
Lance Armstrong vs. Alberto Contador
Someone forgot to tell Contador that Armstrong’s 2009 return to cycling and the Tour de France was supposed to be a feel-good story. Instead, the Spaniard bristled at the suggestion of helping his Astana teammate win another Tour and went for the glory himself — which pissed off Lance something awful. The two sniped at each other throughout the race, which Contador won while Armstrong finished third. Contador later said “I have never admired him and never will.”
Jeff Kent vs. Barry Bonds
Bonds never asked anyone to tell him he’d gotten a big head, but Kent was always willing. The San Francisco Giants stars didn’t mask their dislike for each other and even had a dugout brawl in 2002. The Giants, led by the 2000 NL MVP (Kent) and the 2001 NL MVP (Bonds), managed to make it to the 2002 World Series, but losing to the Angels was the end of this road. Kent escaped the gravitational field of Bonds’ head, leaving for Houston as a free agent.
