Terry may or may not do well at Oregon, but I really think he was fearful of Patrick O'Brien. I recall that POB was getting a lot of attention, and leading up to the weekend that POB was going to visit, Wilson hurried up and committed, I think hoping it might cause POB to think twice about Nebraska.
Since that time, POB was invited to Elite 11 and has gotten a great deal of national attention, as well as by local Nebraska media. While Wilson said early on he was fine with competing with someone in his own class, I think when he saw POB play, he didn't feel he could win the job here.
I doubt POB or Wilson would start right away, but it should add some interesting fuel to the mix if they were both playing in 2016 or 2017 when NU and Oregon play each other.
