Right now, Smith is listed as a Safety on 247sports and Rivals at safety. I'm classifying him as an Athlete due to his consistent role on offense just as much as defense.
Smith earned a scholarship offer only a week ago on the 14th at a camp where the Hokies became his first offer, apparently earning the respect of the coaches enough to earn the offer on the spot. Smith is obviously very athletic- he lines up at quarterback and wide receiver, even at sophomore year. Offensively he's another spread-read-option quarterback- though reading from Rivals, it appears he's more of a general-purpose offensive threat rather than true quarterback.
