FWIW, I am not sure we will get it from our oline this fall.
Last year at this time, there were as many concerns about the defense as there are this year with the offense. Tuitt became a beast and Nix started to realize his potential. The play of those two covered up a lot of other problems, not only on D but also with the rest of the team. With them coming back, IMO the D will be very good this season.
Could the O take a step back?
IMO, Golson will be a pretty good college QB next year. He can run, has a better than average arm, and very good pocket presence. I expect him to play well.
As you noted, ND has questions but a lot of options at the skill positions. They are at least two to three deep in four and five star recruits. Someone should emerge, right?
But few of those folks are very experienced. Chances are they will struggle a bit: missing blocks, dropping passes, fumbling.
A dominant OL man or two could cover up such problems. Not sure we have one. Zach Martin has had a very good college career. Is ND going to be run to his side every time, they need a 3rd and 2? I dunno.
Spring will be interesting. There seems to be a lot of potential on offense but a lot of questions as well. At this point, I am not sure how it will evolve.
