Without your stats it's hard to tell. Maybe you have high speed/agility and poor vision? If you misread a play badly enough due to insufficient vision, a combination of speed/agility/First Step SA would probably cause you to take off in the wrong direction. There are a few CB bugs in the game, but it looks like your guy is just overreacting to everything.
He probly got pump faked on the go route. Alot of CB's don't realize this, if you have low vision and are playing a QB with high pump fake, it could be deadly.
