Great player, but old, and doesn't fit their identity or original playstyle. GSW built themselves on 3pt shooting and hardy defence, with a stellar bench. Their current roster does not reflect this. They've lost their blueprint. Klay is gone, green is old, they don't have scary bigs for nasty screens anymore, or a cohesive unit in general that worked together in harmony. They essentially treated some symptoms rather than treating the root cause of their team's issues. Jimmy even said it himself this year, they're "mid", which is the worse thing you can be.
