I think it one evaluates a player at say #5 at his position and he runs an unexpectedly fast 40, or whatever else, it makes sense to move him up some, or might. I know Holyfield, who looks pretty good on tape, ran a slow 40 and that would be a concern.
I also wonder how different the ESPN guys and their burfle are relative to the real scouts, who may scoff at this notions, if they bother to read any.
When I started working back in the day, I recall looking at how Consumer Reports evaluated laundry detergents, which was what I worked on at the time. Suffice it to say their techniques were amateurish at best and often misleading as to what tests they ran and how. Some were laughable compared to our tests which had been developed over decades.
Their recommendations were similarly laughable, to us, even if in cases they liked one of our products. The folks who did the work were off doing TVs or vacuum cleaners the next week. They just wanted to look impressive and sell magazines.
