I was with you on this list until you got to Nebraska...which leads me to ask what would constitute a "buy" vs a "sell"? Is it each teams movement up or down relative to where they currently sit? if so I guess I agree with you in that Nebraska is at a low and has to get better, I just don't see them ever having the upside they had while in the Big 12 and being able to recruit Texas well. In their hay day they were recruiting the skill guys from Texas and California while getting the giant corn fed lineman as walk on with county scholarships. That isn't likely to ever happen again.
I think Nebraska will start winning maybe 7, 8 or 9 games a year. That's a big jump up from where they've been.
