Let's not even get into the guessing game of what happened a few years ago. It was hashed to death on this board and there were few if any here that had any real/accurate insight to what was happening.
When TG was a sophomore in HS, I heard from a reputable source that she was 90% going to ISU. Then it dropped to 50/50 a year later. I am sure the reason for the decline of interest was that she was hearing what it is like in the lockerroom, and a late night phone call sealed the decision.
