Even though it is quite obvious to anybody who has watched Russell Wilson and Justin Fields that both are capable of pushing the football down the field in the vertical passing game, the way they get it done is quite different. Arm strength and accuracy are often the two things people talk about the most, but the loft and trajectory of the football can make a big difference.
Russell Wilson has always been known for his moon ball, which has much more of an arch to it than Fields’ deep ball. Think of it like the difference between a deep pop fly in baseball and a line drive.
