In his 3-cone drill, Slaton ran a 6.74, a 4.27 short shuttle, and a 35" vertical jump. Slaton also impressed many scouts with his receiving abilities, highlighted with a one-handed grab behind him on a "go route". Slaton's 6.74 three-cone drill time and 1.47 10-yard shuttle time was one of the best by any draft prospect at their respective Pro Days.
