The two defensive players worked out in front of dozens of NFL scouts and coaches at Mississippi State's pro day on Wednesday. The Bulldogs haven't had a first-round pick in the draft since Fletcher Cox in 2012, but both have at least an outside shot at ending that mini-drought. Smith said an underdog mentality can work in preparation for the NFL draft just like it did when trying to become a college star. [...] this fall as a senior, his production exploded with 48 tackles, including 15 for a loss, nine sacks and two interceptions. Mississippi State coach Dan Mullen said he takes pride in taking little-known prospects and then four years later watching them graduate to the NFL.
