The PT TD pass vs. Pitt reminds me of the saying about the blind squirrel finding a nut once in a while.
In fairness, Nunes was a very lightly regarded recruit who was pressed into service because he was all we had.
He took such a beating from the fans, there there arose a pro-Nunes group in reaction who focused on the plays he ran successfully. ("Stop making fun of him, he's not as bad as you all are saying") And that he had a good-looking girlfriend.
Nunes eventually learned, although I'm sure his impulses told him to start running backwards as in the video clip many more times.
The question before us is whether TD can learn. Some of those sacks are unavoidable. The pocket collapses so quickly, Tom Brady would get tackled. But others are avoidable.
