Professional career
Coming out of LSU, Robinson was by the majority of NFL draft experts and scouts to be a fourth or fifth round pick. He received an invitation to the NFL combine and boasted he would run a 4.2 forty-yard dash. Robinson's performance was sub-par and he elected to skip the bench press and wasn't able to complete the short shuttle or three-cone drill after suffering a calf injury. On March 14, 2016, he attended LSU's Pro Day, but held a private workout afterwards due to his tumultuous past with the team. All 32 NFL teams were in attendance as Robinson opted to complete all of the combine and positional drills. He was able to shorten his times in the 40, 20, and 10-yard dash from the combine. Robinson was ranked as the 16th best cornerback prospect in the draft by NFLDraftScout.com. NFL analysts and scouts cited his thin frame, off the field problems, spindly legs, and character concerns were cited as his top issues. Robinson was considered to be one of the top press corners in the draft and was described in scouting reports as a player with a long frame and great man coverage ability. He also has blazing straight line speed and explosiveness.
