A lot of people want to assume that Beck was the weak link in the play-calling, as evidenced by what happened when Warriner went to the booth. However, another possibility is that Warriner was always THE guy, the lead play-caller, so that anything Beck called would first go through Warriner on the field, and then of course Meyer.
It may not have been that Beck was missing stuff that the defense was doing. It may have been that Warriner/Meyer didn't completely trust his judgment yet, due to him being new to the team and what the personnel was capable of versus various looks. Have you ever had a job where people above you were trying to micro-manage everything you did? That situation hardly ever works out, because it puts a damper on intuition and gut instincts. If Beck were given complete control to run the offense, it's possible things would have ran a lot smoother.
I'm not saying that's what the situation was. Nobody but insiders would know that. It's just an equally likely possibility, one that should lead people to suspend judgment at this point. The truth will come out over the next couple of years, when Warriner will likely get a head job somewhere and Beck will either get promoted, stay put while another lead offensive coordinator comes on board (same situation as Fickell, who is valued as an assistant, but isn't really the lead in his coordinator position), or have already moved on to another school.
