This is a two-way street, with a little bit of the chicken and the egg.
A wide receiver can't catch a pass unless the quarterback makes an on-time delivery, but a quarterback can't make the delivery unless the receiver can get open.
With a quarterback, this can vary. The best of the best — NFL passers — can fit the football into the smallest of windows on a consistent basis, regardless of route or defensive concept.
