I figure it's Lee, since he's got the experience and POB hasn't separated from him. Either way, we have a rookie to break in and there will be rookie mistakes. 7 wins tops next season because of this.
Although Lee is new to Nebraska and to this particular system, he is far from a rookie.
Well, his numbers @ Tulane were subpar. ~52% completions and passed for less than 2000 yds per. That was in the American Conference. So, I see no reason to get all "juiced" about him. And the fact that POB hasn't separated from him worries me too. If either actually gets on the field and kicks a$$, I will be surprised. Learning curve time, and we will probably be at a QB disadvantage in most games, like say, Purdue--that guy is pretty darn good and seasoned. jNU QB, same thing, etc. Either should be a better all around passer than TA, but there will be rookie mistakes in real time B1G competition.
If either can pull down 8 wins, I consider it a successful season. Look to '18 for things to get interesting for Big Red.
