Yeah, Rutgers is simply not a good team and are dealing with the same problems as Nebraska (i.e., lack of a big man). Nebraska just happened to have the bigger, albeit uncoordinated, player at the 5.
Now, you take a look at the way Nebraska has played against very good teams in Northwestern, Indiana, Iowa, and today against Rutgers and you have to like how they're playing. They're competing and have held the lead in each game. With Northwestern and Iowa it was simply going a great length of time without scoring; against Indiana, it was the Hoosiers shooting ~70% in the second half. There's not much to be done about Indiana--teams like that can get hot. But, if Miles can find a way to even reduce those scoring droughts, then the next part of the season could be good. If not, then we'll be right where we are.
Nebraska is a good center away from a solid team, which is frustrating.
