Max Unger still remembers the first time he heard Drew Brees call a play in a live huddle.He had gone through the installs and practices. But when the first call came in, it was hard. There was a lot to process, and, well, it took some time to get comfortable with it all."When I got traded, it was my eighth year, I think," Unger said. "I played a lot of football, but it was a pretty good learning curve, just the speed of which you are expected to grasp it and hear the play call and digest all that information and get the line and make the calls. It's hard."
