The skepticism comes from the fact Turay hasn't played football since his freshman season, but Mangan points to Turay's 6-foot-5, 208-pound frame, his athletic accomplishments and a tireless work ethic in assessing why his prospect will be successful.
"The one thing that he has is the natural ability," Mangan said. "Then, put him in a program that is structured for developing talent and making sure the talent goes on to the next level …it is just a great situation for him."
Turay played football as a freshman, but stopped because his mom was fearful of injury. Instead, Turay concentrated on basketball and track and field at Newark Tech, where he is a student. (He plays at Barringer because Newark Tech doesn't have a football team.)
Mangan also said Rutgers coach Kyle Flood, as part of the recruiting pitch, likened Turay to a former NFL standout.
"In speaking with coach Flood, he gave a comparison to Jason Taylor," Mangan said. "They told Jason Taylor that he was too small. With Kemoko, they're going to put him in a weightlifting program and they're going to have him gain 30 pounds and be able to win 1-on-1 battles with a left tackle."
The transition back to the football field and then onto college should be aided by the defensive scheme Barringer will run.
"Some of the things they'll teach him, we're teaching him the same things," Mangan said. "He's going to be our hash-end. He's going to be a guy that boxes the play, that chases down the guy from behind. With his track background, running is not a problem. His explosiveness from being a triple jump champion, he can transfer those things. He runs well, he bends well."
Turay won the Group I sectional triple jump title with a jump of 44 feet, 4 ½ inches, and finished 16th in the nation 43-4 ¼) three weeks ago at the New Balance Outdoor nationals. He also won the sectional long jump with a jump or 21 feet, 11 ½ inches.
At the Rutgers one-day camp, Turay broad jumped more than 10 feet, a stellar mark.
And the effort Turay put into track, Mangan said shows he will work hard on the football field.
"He comes from a great background. He has great work ethic," Mangan said. "His father gives him some great structure. He put him on a path and motivated him to finish everything he does, and doing a great job doing it. Him getting back out there playing football, (and) that adds to it.
"He has a relentless motor and you can't stop him on the high school level. That position Rutgers is going to play him at, that rush end, it's a great opportunity for him to box the play and feel the play. The sky is the limit. They were so excited to get him because he fits what they want to do."
