I listened to Hadsell’s weekly live show last night and he touched on it. Talked about how it’s great for track and field to get this exposure. Brought up Bo Jackson which is a great comparison.
Bo was arguably the fastest NFL player of all time. Ran 4.12 at combine. Ran indoor track at Auburn and qualified for ncaas twice indoors at 60y but never made the finals. Bo was 6-2, 224. Essentially same size as DK. Too big. DK could potentially be even leading at 40m but will struggle past 70m.
A few of these guys on your list are also “big” guys that were very fast on the field but not so fast in limited outdoor 100m action. Bo only tan a few meets outdoors as an example but did run around 6.15 for 55m. Personally I would like to see Grant Holloway in that 100m. Was great football player but concentrates on hurdles. I think he would easily beat DK even outside his main event.
