Brady has never thrown deep to Branch. His long receptions are generally because of YAC. Ocho has promise as a deep threat if he and Brady can get on the same page.
Sadly Tom never really throws deep(in the air over 20 yards) and when he does it is too someone you wouldn't start(post-moss era). This year it will be Matthew Slater and Taylor Price. Branch and Ocho will run similar routes on oppo sides with Welker controlling the crossing routes.
