In essense what Prince is saying (and what he's implied a lot) is you can take decent big HS kids (6-4 or so, 220 or so) that have good feet and work ethic and "make" good offensive lineman. However, you can't make a guy run a 4.3, you've got to recruit it, and its his opinion you need a lot of guys with that kind of speed (on both sides of the ball) to win college football games. I don't think he's so far off.
