Techrod has a good point. First though, I welcome the kid in and am glad he chose Georgia Tech!!
But when trying to judge ability, the list of other schools that truly "offered" is important in "trying" to evaluate how good a player will be. Obviously, it is not exact, i.e. GT was the ONLY D-1 school to offer Jerry Mays a scholarship (we beat Furman and Western Carolina if memory serves) and he turned out to be a great one.
However, it is very typical for a kid to make a list of "Florida, Miami, Tennessee, USC, Michigan and Kentucky", when in reality the player is interested in the first 5, but only the last one will actually offer a scholarship or has interest in him. And I believe that is Techrod's point. Without seeing any of these players play in person, that is about the only thing one can go by.
