Good question. It's just my own opinion, as I said. I'm not speaking for anyone. Just a few days ago, this subject came up and a few former players I was talking to disagreed with me about this in some regards. They figured Anderson at our #2 back, if there is such a thing.
Whatever the case, he will contribute this year for sure. Key word is 'significantly". Don't take that as any sorta negative unless you expected him to start and to have a huge impact. Two things: 1. Justin Jackson and Warren Long. 2. How well does he know the offense?
Regarding #1, I'm very high on Warren Long and he could feature in the backfield on many Big Ten Teams, but Jackson is in front. I'm fairly certain that Long is going to get the bulk of non-Jackson carries as he not only can spell Jackson but he has a skillset that sets him different from Jackson as well. In my opinion, Anderson is going to be used mostly if not exclusively as a RB and won't be able to steal many plays in the slot since we have that covered as well. Key word 'many'. Will he get some slot reps? Yes, in fact in this offense the RB can line up anywhere. But the level of competition, it seems to me, says he will get about 15 reps a game until he learns the complete offensive package [insert redshirt freshman], don't take that for granted. In other words, I see Anderson as our #3 back. He has 4 years here but the talent at NU is pretty good. I'm sure he will eventually find a way to start, right now, no way. I'm thinking he will see about 15 plays a game, and that doesn't include special team plays. Of course, he is a talent and I haven't seen the game plan so if we shift the offense to several two back sets then he will see the field more. That is reasonable but I just don't have that info.
I do know this, John Moten is also solid, and if he keeps his shirt on, then it is only because the coaches are very confident of Anderson.
