He added: "I look at it, like I mentioned before, we've made considerable improvement in many areas offensively," Fox said. "One of the frustrating things is that we've been with four quarterbacks. I go all the way back to Connor Shaw, because he was in the mix as late as the third preseason game. Three different quarterbacks starting, I think each of them won a game -- as you look back, that's probably the ultimate team game. You got 11 guys out there at once. The continuity and consistency helps when there is continuity and consistency. And that's not been the case."
