I mean, I know they reached the Conference Finals, but if they end up choking on a 3-1 series lead and Westbrook's shot selection and BBIQ is a big reason why they end up losing the series, I can't see a better scenario for Durant leaving than that. Those are things that won't be fixed with the current makeup of that team.
Many of us have long said that Westbrook and Durant aren't great together. I'd love to have either of them as the best player on our team, but I just don't think they mesh well. A choke job in the WCF might finally be the push that Durant needed to leave.
