Spurs forward Kawhi Leonard, the newly minted NBA Finals MVP, faced criticism from the regular season MVP before he could even finish his championship cigar.

Leonard has been touted because of his NBA Finals performance, which featured one of the all-time turnarounds. Leonard scored nine points each in Games 1 and 2, only to go on to produce 23.7 points over the final three games and end the series with averages of 17.8 points and 6.4 rebounds.

Thunder star Kevin Durant saw that performance as more of a system-based result, and he said as much in a casual Twitter debate. 

The comment is interesting because Spurs coach Gregg Popovich has made a point of telling the media that the Spurs don't run any plays for Leonard, which means that most of his production must come outside of the "system" that defines the Spurs' offense. 

One other thing to keep in mind: The Thunder were knocked out of the playoffs by the Spurs, losing to the eventual cha

mps in the Western Conference Finals. Durant's wounds are still fresh.

That said, he has an opinion just like everyone else on Twitter. The only difference — and this is a big difference — is that he happens to be one of the best basketball players in the world. Everything that goes along with being Kevin Durant, including Twitter comments, are dissected at the highest level. 

And while Durant later deleted the tweet, this was harmless banter. Popovich and the Spurs have fielded questions about their "system basketball" all year, and that isn't likely to change anytime soon.
