I wouldn't even necessarily say that his style of play is not conducive to winning, just that a team built around him has to be built in a very specific way, and the Thunder are not built in that way. In the "modern" NBA, a championship contender that has Westbrook as its best player would have to be built more like the 17-18 Celtics.
I have long felt like nearly all general managers and coaches in the NBA are completely lacking in imagination. Now, to be completely fair, lack of access to the necessary players is a major problem: sometimes, you might have a concept that you can't make work without a complementary player who's under contract for somebody else. That said, I feel like I could build a championship team in which any one of the Top 15 players in the NBA is the best player on the team. In fact, given access to the entire NBA, I feel like I wouldn't even need a second Top 15 player to do it.
