At LSU's pro day, Sheppard ran the 40-yard dash twice in 4.46 seconds. He had a 38 1/2-inch vertical, a 10-foot-2 broad jump, a 4.37-second short shuttle, a 7.09-second three-cone drill and did eight reps of 225 pounds on the bench. At the pro day, he did both wide receiver and defensive back workouts, and scouts think Sheppard's best position in the NFL could be at defensive back.
Future Hall of Famer
A once-in-a-generation type prospect who could change how his position is played
An impact player with the ability/intangibles to become a Pro Bowl player. Expect to start immediately except in a unique situation (i.e. behind a veteran starter).
A quality player who will contribute to the team early on and is expected to develop into a starter. A reliable player who brings value to the position.
A prospect with the ability to make team as a backup/role player. Needs to be a special teams contributor at applicable positions. Players in the high range of this category might have long-term potential.
A player with solid measurables, intangibles, college achievements, or a developing skill that warrants an opportunity in an NFL camp. In the right situation, he could earn a place on a 53-man roster, but most likely will be a practice squad player or a camp body.
