Kawhi Leonard, San Antonio Spurs
This is of course assuming that Kawhi Leonard returns to the form we saw before his prolonged absence due to that nagging quad injury. But if you think even that version of Leonard couldn’t stop LeBron James, let us remind you of the way Leonard actually took over the 2014 NBA Finals, going mano-a-mano with James and leading the Spurs to beat James’ Heat. When healthy, there’s no better one-on-one defender in the NBA than Kawhi Leonard, which is why so many teams would be willing to give up premium assets to take him off the hands of the Spurs. It’s also why the Spurs are so reluctant to trade him, even though the relationship seems to be irreparably damaged.
