In the first few years of the KO coaching era, he had Blaney, Hobbs and Miller with him, all of whom had considerable head coaching experience. Over time they were replaced with guys who had a fraction of the experience and knowledge. The poor results during the last couple years speak for themselves.
Hurley has a great staff. I'm sure they offer suggestions and insight. Hurley's passion for the game might make him a bit stubborn though. That said, a fully healthy roster with Bouk, Jackson and Akok would probably make his in game coaching look much better. The team is 8-3 despite not getting anything from that trio recently. While I agree that Hurley's in game coaching could use a little improvement, I fully believe that having all of our impact players healthy would have an even greater effect.
