Wikipedia says the same thing - Ismail was also a track star at the University of Notre Dame, where he ran the 100 meters in 10.2 seconds. He also competed in the 55 meters, with a personal best of 6.07 seconds. At the 1991 NCAA Indoor Track Championships, he finished 2nd in the 55-meter sprint.
And the most important parts... CJ's numbers are from his JR year, and CJ is not the next Rocket but their track speed could be comparable.
So even if this was Raghib's HS time it doesn't matter. Also, e-times weren't even used in HS. Now nearly every track meet I attend is using computer timing vs hand times.
Ultimately, none of this really matters. CJ can come to ND and be everything the Rocket was and people will still slight him because of nostalgia, its how fandom works. The Rocket is probably the single greatest reason I became an ND fan. Doesn't mean I won't allow people to debate if there will be another kid to come along and be as great. The chances of that happening are ultra slim but its the hope that makes the games that much more worth watching.
