OG Demetrius Knox, Worth (Texas) All Saints Episcopal
Why Brown has an edge:
Brown is a defensive lineman with the complete package; he has ideal size and great strength, and he is very fast off the ball. His initial burst combined with refined technique makes him a handful for any offensive lineman to handle, and it's even more cumbersome in a camp pass-rushing setting. The only way for Knox to slow him down will be to get his hands on Brown early and often, and even then Brown will still have the strength to make it very interesting.

Why Knox has an edge:
http://vmedia.rivals.com/uploads/880/1379042.jpg" width="60" height="72" align="right">At 6-4, 287 pounds, Knox has excellent footwork for a projected interior lineman and actually starts at right tackle for his high school squad. His long arms allow him to get into defenders very quickly, and he packs a powerful initial punch. Whether he is in pass protection or driving off the ball, he plays with advanced technique and does a good job of staying low, maintaining a wide base and getting underneath his opponent.
-- Jason Howell, Southwest recruiting analyst
Overall edge:
This is technique vs. technique because both prospects are very well coached and clearly work on their games often. Brown's burst off the ball and violent hands will be combated by Knox's long arms and ability to punch off the snap. It's harder to be dominant as an interior defensive lineman in a camp setting simply because of the bodies surrounding you, but Brown has the edge here because he's so good initially with his hands and he can get skinny in the hole when he needs to, despite his great size.
-- Mike Farrell, national recruiting analyst
