My two cents is that while Romo does have a good sense, many of the predictions are smoke and mirrors sprinkled with hype.
As examples, there were two Gronk plays where he lined up wide and Romo is credited for "calling the play".
On the first instance Romo is credited for predicting Gronk would be wide, but in fact, he said this while cameras were focused on something else. By the time they showed Gronk he was already set wide and would not have time to have moved and get in this position. In other words Romo saw Gronk wide and made an observation. Then Romo said if Gronk is doubled (he was, but late safety help) Brady was going to find Edelman over the middle. Brady threw long to Gronk and Nantz began crediting Tony for being having called this.
In the second instance Romo was plain wrong. He pointed out Gronk was wide and said if the safety moved up, Brady would go long. The safety moved up and Brady caught Gronk over the middle.
In these situations (3rd and long) Brady is going to either Gronk, Edelman, or White. Since White was non existent and Edelman had caught the last two, it was pretty safe to focus on Gronk. Even then Romo was mostly wrong.
