Targets aren't created equal for fantasy football. It's easier to complete a pass over the middle compared to near the sideline. As you can see in the chart below, "sideline targets" are worth 1.58 PPR points on average, while "middle targets" are worth 1.83 PPR points, a difference of +0.25 PPR points per target. That can add up.
Air yards -- the distance the ball traveled from the line of scrimmage to the receiver at the catch point -- are also worth tracking. The further downfield a target travels, the more valuable it is. On average, "shallow targets" (under 10 air yards) are worth 1.
