Sometimes versatility is a curse as well as a blessing. Riddick came to Notre Dame in a time where the team had more impact running backs than receivers, so coaches moved him outside for his sophomore and junior seasons to take advantage of his athleticism in the slot. But as a senior, the team allowed him to spend more time at his more natural position of running back.
Riddick ran for over 4,000 yards in high school, while also earning all-state accolades in New Jersey as a defensive back as a sophomore. He was a reserve running back in his true freshman season, playing in all 12 games and starting the finale against Stanford, totaling 160 yards on 29 carries (5.5 per) while also serving as the team’s primary kick returner (22.9-year average). Riddick missed four games with a sprained right ankle as a sophomore, but started eight of the nine games played at receiver (40-414, 3 TD). He again sat two games due to a hamstring injury in 2011, starting nine of the 11 games in which he was healthy enough to play (38-436, 3 TD). Riddick split time in the backfield with Cierre Wood as a senior, and ultimately saw 190 carries for 917 yards and five touchdowns. As a pass catcher, he caught 36 passes for 370 yards and two touchdowns.
Slasher with some open-field speed. Flashes a strong cut and acceleration to get through a hole. Has value as a receiver out of the backfield with his experience as a slot man. Freezes linebacker with his wiggle in his route, can adjust to poor throws to bring them in. Willing to lower his pads and lean for the extra yard in short-yardage situations, also not afraid to bring his shoulder or step through a would-be tackler. Runs behind his pads, and keeps his legs churning when hit. Finds a defensive lineman to chip via a thrown shoulder in pass protection.
Longer legs and leaner overall build than many teams prefer in a tailback. Upright runner who doesn’t tuck the ball away in the open field. Gets himself off-balance with too much dancing in space. Stands up to blitzers in pass protection but won’t anchor against stronger linebackers.
Riddick made some plays as an inside receiver in his sophomore (40 catches, 414 yards, 3 TD) and junior (38-436, 3 TD) seasons, but the former all-state running back from New Jersey returned to his natural position for his senior year, while also seeing snaps at receiver when Cierre Wood was in. Riddick's chess piece potential will likely earn him a draftable grade.
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.
