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 ass, 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.
Obviously hasn't looked at the 2018 schedule yet...
