I think you got it right. Also you have to remember the Double Standard Rule. Lewis doesn't have an offer from a Big Ten school other than Illinois, but you get an exemption if you're from out of state or play higher than 1A ball. Therefore, Lewis is also Big Ten caliber.
Iowa State and Auburn have both offered. Iowa State better program than us, and Auburn has gotten some 5* recently. Chastain has an Utah offer, maybe?
