Antonio Brown is renowned for his route running and ability to gain separation against bigger and faster defensive backs. A true technician, Brown puts a full array of skill on display every time he steps out on the field putting very good defenders in the spin cycle with regularity.
Route running in the NFL takes a considerable degree of dedication and nuance. NFL defenders are able to watch every snap and every target for a specific player for their entire career. If a receiver doesn’t vary his releases and route stems he will get beat by smart defensive backs.
