Why dont you even read what Wikipedia says. That information there is from scout.com and rivals.
Here is his scout.com profile -

You do know what "sources" for articles or information are, right? Thats why wikipedia links them.
See how it says 4.40 40, and that he is 6'1? Those are what info they have on him says he was coming out of high school. Unless he shrunk over an inch since high school, those numbers may have been inflated.
Here is his rivals.com link -

The rivals one is another one from when he was a senior in high school and being recruited.
This one has him at an inch shorter and running a 4.39 instead of a 4.4
The only actual height/weight/40 time we have that was timed and measured by nfl scouts was the 5112 height, 212 weight, and 4.51 40. And thats not knocking brown, I would love to know how he did at the actual combine, but I cant find the info.
