I don't disagree, it's good to get some nearby projects and I think they're more likely overall to contribute. Aren't 3 of those guys committed as walk ons? They're willing to join the the team and work for a scholarship, a kid from SC isn't going to come halfway across the country without one. This way we get both.
There's also a difference between a project that could turn into a great tackle and a project who can only play Guard. Fritzche is athletic enough to be a great Tackle - obviously that's not guaranteed, but it's a possibility. Nothing against the walk-on commits, but who was the last walk-on Tackle who contributed in a big way? We've churned out some really good Centers and Guards, not any Tackles that I can recall.
