[*]I think many of Brady's struggles is his lack of confidence in his receivers and his desire to do too much. Once the receivers started to click, Brady started to become money (except three goalline throws which two were due to poor pass protection.
I think "confidence" is the wrong word. I think it's more a matter of familiarity. He doesn't know exactly how his receivers will separate from coverage or how they will read the coverage. Therefore, it takes him longer to make his reads, because he has to think about it. It also leads to missed connections. For example,
I think it was Thompkins who was running a slant from the outside; the underneath defender had carried the deep inside route so far upfield that there was nobody nearby. Brady expected Thompkins to continue his route and catch the ball in stride, but Thompkins settled into the zone seam, making his literal read against a zone. Brady was confidently expecting Thompkins to adjust his read based on the blown coverage and keep moving, but KT needed that play to learn it. Similarly, on the miss with Dobson in the end zone, he ran to the open space vacated by the safety, but Brady threw the conservative low ball, figuring Dobson would be there to catch the TD. In this case, Dobson read the coverage, and TB made the automatic throw, rather than the other way around. I'm not sure whose fault that one is. If that were Welker, Branch, Thompkins, or Edelman, you would expect the low ball to be the right one. With Gronk, it would be the high ball, and I suspect that with Dobson breaking for the back of the end zone, the high ball would be the right one, too. That's a familiarity issue, not a trust issue.
That's not saying there aren't confidence issues, too. That play where both Edelman and Thompkins were breaking open downfiled, and Tom was focused on the higher-percentage ball, perhaps was a confidence issue. I just think that's less an issue and that the talk of confidence and trust (in general) is overblown. He's giving those guys chances to make plays. That's confident enough for me.
