My vague recollection is that Iguodala shot up the rankings later in his HS career, was overshadowed by McBride before that. I want to say (very vague memory) Self didn't recruit him right away because of questions about his offensive skill. Definitely more in the spotlight by his senior year than Lincoln Williams for sure, but it's not like Williams didn't have big time offers ... and would have had more/bigger offers and better ranking but for his shaky academics.
And sorry for my geographic shorthand ... to us Chicago area folks, anything south of I-80 and north of St. Louis is central Illinois.
