I do not see it taking a lot either. OL improvement. While that unit is replacing a couple guys, it also underperformed so I hope for improvement with new guys.
With a QB that is a legitimate threat in the zone-read game, the OL could look much improved even if it isn't. When a defense has to respect the QB as a running back, that will give Justin Jackson a few more milliseconds and that's all he needs to bust more big plays. This can turn a lot of 1-3 yard gainers into 10+ gainers, and the cumulative effect of that over a full game is huge. The QB doesn't even have to carry the ball that much to change the game. He just needs to be a credible threat. That being said, yes, OL improvement would be huge.
QB while on paper, our QB situation should have been better last year, TS was not healthy. Even though our QB will have limited experience, if he is healthy, it is likely an area of improvement,.
TS was good at many things, but his biggest weaknesses (even when healthy) was an inability to make a play with the ball in his hands and poor pocket presence. These are the two skill sets our poor OL and WR play a year ago made most indispensable. If our QBs are better in those two areas, they could fall short of TS in many other areas and still be a better fit for the offense and improve productivity.
WR, we lost our top guy before the season started and others along the way. Other guys underperformed and our our 3rd or 4th option became our first until he too went down. Would not take much to be an improvement.
This group was a complete mess last years with an insane number of injuries, (what I thought were) proven veterans playing like freshman, young guys totally blowing their opportunity when it came early due to injury. Last year was the worst season I've seen for an NU WR group for at least 20 years. The bar is incredibly low here, and I don't even see how it is possible for this group not to improve from last year. If we discover a guy or two that can occasionally turn a 3-5 yard dink pass into a 10-15 yard gainer, that would be great. Perhaps a Soloman Vault could be one of those type of guys.
RB, we likely have more depth but performance would still depend on OL. We also do not have the distraction of losing VM right before the season started. Only have to improve a little to realy improve our O.
It's amazing how much VM popping 2-3 big gainers per game in 2012 could make an otherwise unproductive offense appear efficient or even potent at times.. Many of the problems that plagued the offense in 2013 and 2014 were present in 2012. Having a play-maker change field position a few times per game really masks inconsistency. Hopefully Justin Jackson and a few of the other young guys can start making some big plays, so the offense doesn't have to convert 7-8 third downs on a series to score a TD.
D will likely depend on the recovery of our DTs and again staying healthy.
I think we'll be fine here even if we have to rely on some of the younger guys more than we like. I think this defense could be really good. The secondary looks very deep and talented beyond just the starters. The DE group is very deep and full of play-makers with complimentary skills. I really like Anthony Walker, and I like the way our young LBs looked in the spring. The D could be special.
On the other hand, we do have a harder schedule (at least OOC but we really did not do anything with it last year. It would not be hard to improve enough to surprise some people.
We'll be at least 2-2 in non-conference like last year. We essentially swap Cal and Notre Dame for Stanford and Duke. Ball State is no Northern Illinois. Our OOC schedule is arguably a push versus 2014. We play the exact same conference teams we played in 2014. We just switch the home and away for each. We get Stanford at home in the first game of the season at an 11:00 AM game. If that can't focus an NU team in the off season, I don't know what can. Duke loses a number of very good players to graduation, so they could easily regress a bit. They won 9 games a year ago, but they beat a lot of bad teams. Their only good win was against Georgia Tech.
All of our B1G home games are very winnable, and we've played pretty well @ Nebraska and Michigan in recent years. Wisconsin doesn't scare me, and we beat them last year (when they had Melvin Gordon). Both Nebraska and Wisconsin are breaking in new coaching staffs, so that could put them behind schedule. We don't play Ohio State or Michigan State in cross-over games. (Wisconsin and Iowa are the other two West teams that skip both Ohio State or Michigan State, which makes our games against each of them that much more important.)
In short, we have a comparable schedule to last year, but the two more traditional West division power teams (UNL and UW) are breaking in new coaches and PSU is still living with the consequences of scholarships reductions and recruiting challenges several years ago.
