Agreed. If he were a legit 4.4 he would be running a 10.15 - 10.2 hundred meters and would be the track star of the state. Nebraska may produce one athlete per 5 years that runs a legit, electronic 4.40. Of course, the number per year that report a 4.4 is quite high. They lie.When you see a 40 yard dash time off of an internet site, you need to add .25 seconds to it.
Jeremy Macklin ran a 4.40 at the NFL combine. There is no way this kid runs like Macklin.
An electronic 4.40 is rare --- even in the NFL. Certainly the average WR in the NFL does not run an electronic 4.40.
This young man is quite more likely an electronic 4.65 or so. And, as it were, that is pretty fast.
