Professional career
Pre-draft
Prior to his junior year, Amerson was widely projected to be a top-10 selection in the 2013 NFL draft.[5][6][7] However, his draft stock dropped after a mediocre junior season. Coming out of North Carolina State, the majority of analysts and scouts projected Amerson as a second or third round pick. He was ranked the ninth-best cornerback by NFLDraftScout.com. Amerson was invited to the NFL Scouting Combine and completed most of the workouts and drills before injuring his groin that inevitably kept him from doing the three-cone drill and short shuttle. He also participated at NC State's Pro Day and made up the three-cone drill and short shuttle while also improving on his combine numbers in the vertical and broad jump.[8]
On May 7, 2013, the Washington Redskins signed him to a four-year, $3.85 million contract with a signing bonus of $1.10 million.[11][12][13]
