Sometimes, young offensive line recruits can be a little bit hard to project. It’s really the only part of football dependent primarily on physical attributes (strength, size), and when it comes to high school football players, you’ve got a massive pool of players that aren’t done developing physically yet. Recruits get bigger, and they get stronger, which then, in turn, makes them better if they play on the offensive line.
That’s why so much of line recruiting is often projection. It’s trait hunting, looking for things that could make for a great lineman, once the weight and strength gets added to what is usually a not-yet-complete frame.
