I would agree he didn't recruit well at Nebraska. I didn't take issue with that at all. However him taking Casey isn't an indication of his poor recruiting as you tried to say. The fact he beat out a pile of other teams, including USC and Auburn, actually is a feather in his recruiting cap.
All of that aside, I still think a coaches recruiting ability has as much or more to do with their location and how much the team values them monetarily in this current NIL environment we are in.
I'm guessing he ends up recruiting very well at Oregon with the financial backing they have and the proximity to Polynesian recruits. I guess time will tell.
