I’m sure the answer to this question is buried somewhere in the 15 page Gebbia thread but I’m going anyway: Did anyone else hear that Gebbia didn’t want to leave Nebraska but his Dad wanted him to leave. This is sad-nothing like helicopter parents.
It's a mixture of that and coaches hounding him once Adrian was named starter. Coaches are just as concerned with tracking guys they lost in the recruiting trail for reasons like this. I am sure coaches called him and his dad and explained why transferring now was better.
