3. Kawhi Leonard vs. the Spurs
Kawhi Leonard was supposed to be the next great player that lead the Spurs franchise for another decade after the retirement of Tim Duncan.
Last season, that great plan was foiled as Leonard lost all of his trust in the Spurs after feeling that they mishandled his injury. Leonard ended up deciding that he could no longer play for the organization and forced his way out of San Antonio via a trade.
