Kobe Bryant once summed up his approach to personal relationships as follows: "Friends come and go, but banners hang forever."

With five championships on his resume, it's hard to argue with the results, but not every player shares his philosophy.

Look around the NBA and you'll see plenty of friendships - most between teammates, but many others among opponents. The most famous quartet of pals in professional sports even has its own nickname; a classic offseason vacation photo led to LeBron James, Carmelo Anthony, Chris Paul, and Dwyane Wade being collectively dubbed the Banana Boat.

Former Toronto Raptors teammates Kyle Lowry and DeMar DeRozan, who were broken up after DeRozan was dealt to the San Antonio Spurs, are considered two of the closest friends in the league. Earlier this season, savvy viewers spotted Lowry performing his part of the old pregame routine he'd developed with DeRozan.

Asked about the gesture, Lowry responded: "He's always going to be my best friend."

And then there's the Los Angeles Clippers' pairing of towering center Boban Marjanovic and affable forward Tobias Harris, known colloquially as Bobi and Tobi. They've assumed the mantle of the league's best-known BFFs, and have gone into great detail about what makes their kinship work.
