The end of this post isn’t very convincing. You’re sure there are others we were trying to hide on defense? Whom? And how much less significant are those players than someone in the starting and closing lineups? For example, Niang isn’t a good defender, but when you weigh the importance of his role and the number of minutes he plays, then he slides way behind Conley on the list of concerns. Bradley wasn’t good, but we didn’t hide him and he didn’t play many minutes. Etc.
A lot of your other points point back to Conley and/or what it took to put him on this team. I feel like you’ve only gotta follow through on most of your own arguments, rewatch the games, and then you’ll basically be in agreement with my position.
