While the offense had its moments in 2016, it wasn't very good. In the red zone, it was among the worst in the country. There's a huge amount of room for improvement, but it's tough to anticipate what's going to happen offensively because a) the OL will have a very different look without Feeney, Rogers and Camiel (Camiel's injury cost him most of the 2016 season but he was a huge contributor the year before) and b) the progression, maturation and development of Lagow remains to be seen. With respect to the OL, Cronk and Brandon Knight are very talented (we'll see how Knight looks post-injury), Wes Martin started every game last year, and Baker and Stepaniak saw plenty of action so this OL is hardly green. Stover and Littlejohn may be ready to step up and make important contributions as well.
With respect to skill players, things look very good. Westbrook and Cobbs are two of the best WRs in the conference, and they're tall targets for Lagow to hit. Hale is athletic and tall as well. Harris is coming back from two ACL injuries so it's difficult to predict how much of a factor he'll be. There are some post-injury questions with respect to Patrick as the featured RB, but if he's fully healed and ready to go, watch out. There's some depth at RB with Majette, Brookins, Gest, Natee and Rodriguez (I feel like I'm forgetting someone else) all ready to contribute.
We went bowling last year because of Allen and the defense. The defense may have to bear the load again this year. But there's potential, at least, for significant offensive improvement provided we can keep the injury bug away. Colorado and others will jump all over me for saying this, but if the offense stays relatively healthy, Lagow improves (translation: fewer picks) after a year of B1G play under his belt, and the OL is serviceable, this team has a ceiling the likes of which we haven't seen at IU in decades. I know - - those are some important variables, qualifiers and question marks, but far fewer variables than we've had in the many years I've been following IU football. Having a defense - - finally - - changes the entire equation.
