Football Route Tree
A route tree in football is a common set list of routes for passing plays by the offense that assigns a number value of 1-9 to each route. Route trees are used to refer to specific routes and route combinations in a timely manner, as well as establish a common language regarding route patterns.
Routes in the Route Tree
The hitch route is not always shown on route trees because it is very simple; the receiver takes a couple hard steps forward before turning inside to catch the ball.
The slant (also known as the "quick in" or "crossing route") is one of the most common routes in all of football. The receiver of a slant needs to move quickly when the ball is snapped so they may catch the ball before the defense can react.
PRO TIP: In routes numbered 3-8, the receiver will want to make it seem like he is running a #9 in order to create more separation from the defensive back off the break.
Also referred to as a "dig" or "deep-in," the #6 route is the same as a #5, except the receiver breaks to the inside. This can be a dangerous route for a receiver if they are not aware of their surroundings-cutting into the middle of a defense can lead to big hits and injuries.
Although there are many names for a #9 route-the "go", "fade", and "fly" are just a few-it is the most basic route to understand. The receiver simply runs in a straight line to try and outrun their defender. The go route is high risk, but high reward.
