Yes, I did say that I've lost confidence in Emery/Trestman due to their views on Cutler, but that as nothing to do with Trestman being a talented play caller and improving the O. I haven't lost any faith in Trestman's system nor his ability to call plays. What I don't have faith in is their faith in Cutler to run it.
IMO it's incredibly stupid for Trest/Emery to have placed their careers in Jays hands. Jay has done nothing to earn that kind of commitment and they would have been wise to leave themselves some room to distance themselves from him if need be. I simply see no reason to assume that he'll ever be anything more than an inconsistent turnover prone QB, who while above average in physical talent, is average at best when it comes to the cerebral and mechanical aspects of the position.
