Kerr seems lost sometimes. He relies way too much on the player's talent if that makes sense.
What I mean is when guys like Steph, KD, Klay etc. are on, Kerr doesn't even have to coach. But when they're off, Kerr doesn't actually know how to coach to set them back up for success. If the players are off Kerr just always seems dumbfounded on what to do. He never sets up any plays, he never does proper rotations for the right moments, he just relies on Steph, KD, Klay, and Draymond to not need him.
Last year in the playoffs for example, the team seemed way more of a fluid basketball team when Kerr was out during the playoffs and Mike Brown was in. I was even talking about it in posts in this thread at the time.
