First of all. Whatever WR did as a true freshman really had nothing to do with development. He was suppose to be like Rondale Moore. They trained together and are friends. I am not saying he doesn't have a lot of the same attributes that Rondale Moore has, but he is not as good. He just isn't. That has nothing to do with development at Nebraska.
On to your second paragraph, I am going to leave PJ and Minnesota out of this equation because I would not say a 2 year winning streak is consistently better. PJ in his 4 years at Minnesota has had 1 really good year so lets not throw him in with Iowa and Wisconsin just yet.
I would agree that Iowa and Wisconsin have done a lot better job of developing players, in particular offensive and defensive linemen ever since Nebraska had been in the B1G. The reason that is is because both of those teams have been doing the exact same thing in their development for a minimum of 20 years. Iowa has had 1 coach since 1999. Wisconsin has had 1 system since 1990. That is the big difference. Nebraska since Farniok has been here has had 2 different HC, 2 different O-line coaches and most importantly 2 completely different offensive systems.
I guess I think Farniok has played OK. No not all B1G by any stretch of the imagination, but OK. I personally never put a lot of stock inrecruiting hype of offensive and defensive linemen. They both need a ton of development even if they are a 4*. There is just too many variables involved with linemen.
