There's a tendency to think that NBA opponents, steeped as they are in various levels of competition and psychological edges. But, for the most part, these players get along, even if they sometimes get at each other's throats in the heat of the moment. They're colleagues, after all. In another era, we called that general respect and friendship sportsmanship.
Stephen Jackson of the San Antonio Spurs apparently likes Kevin Durant a lot. So much, in fact, that he wrote "World's Biggest Kevin Durant Fan" on a crab bib emblazoned with "LET'S GET CRACKIN'" in red type, took a photo, and put it on Instagram.
You might remember that Durant's Thunder dispatched the Spurs in six games in the Western Conference Finals. It's very good of Jackson to give credit to KD. On the other hand, I'm not sure you'd call this sportsmanship. I would say "one of the greatest images of the year," myself.
