One of them was spatial awareness, which translates in several aspects of the game, including how well a quarterback can assess a defense before the snap...Another area in which Purdy excelled was distraction control. “Those are the guys — and Drew Brees was one of those — who, the pocket, the world could be collapsing around them and they can just maintain that steely focus on what they’re supposed to be doing,” Ally said....Finally, Purdy was especially impressive when it came to depth perception speed....“He was in some pretty elite company,” Ally said.
