Antonio Brown is one of the most productive receivers in NFL history. His 582 receptions and 7,848 receiving yards since 2013 are far and away the best in the league. He is an incredible football player, but he doesn't possess the pure jaw-dropping athleticism of guys like Julio Jones and Dez Bryant—a fact that was abundantly clear at the 2010 NFL Combine.
For starters, Brown was one of the smallest receivers there, measuring 5-foot-10 and 186 pounds. His 4.56 40-Yard Dash was unremarkable for a player of his stature, and his 108-inch Broad Jump was the worst result at his position by a full 9 inches. The only drill in which he performed decently was the 20-yard Shuttle, where his result of 4.18 seconds ranked seventh among receivers.
Many scouts left the Combine thinking that Brown was too small and too un-athletic to be an impact player in the NFL, allowing the Pittsburgh Steelers to pick him up in the 6th round of the Draft. Brown is still rarely the fastest or strongest player on the field, but his elite vision, instincts and route-running make him a nightmare for opposing defenses.
