The guys both were tested under the same circumstances without bias, yet you want to ignore one guy's numbers. Why is that? Oh, because you are letting your personal bias even get to the point where you dispute facts because they don't fit your agenda.
And for the record, these aren't stats...they are measurements.
Can you tell me how the measurements lie? That Costa didn't really put the bar up 30 times, or have a better vertical and broad jump? The running numbers, sure, there can be some questioning unless everything was done on the exact same day, exact same conditions, exact some timing equipment...but it's obvious when all the numbers are looked at you are looking at two pretty amazingly athletic big men.
