10.87 May of 2024 for Koi as a senior. Cooper's time was also as a senior. Both of them have multiple times in the low 11's. I think they are likely comparable. Very similar size too. My eye test is that Cooper is slightly faster, but we'll see. Koi seems very quick and instinctive and seems like a very good leaper, but Cooper was that way too. Hey, if Koi turns into Cooper or, even better, Robert Smith, we'll all be very happy! Both amazing athlete's and football players.
Cooper ran mid-4.4 40's while Smith ran upper 4.5's for the NFL draft. I feel like the training for the 40 has gotten better though and times have come down. Everything is such a science nowadays. It was posted here previously on GopherHole that Koi has already run a 4.54 40. My money says he is around a 4.5 40 when he's tested for the draft in a few years. That's plenty fast enough for an NFL safety.
