The 2015 schedule was favorable but unless something major changes our schedule every year is a little on the favorable side. We have Clemson or FSU sometimes but they are the only teams in the Atlantic that are consistently ranked. Now Miami seems to be getting good again but VT is the only other team in the Coastal that is consistently ranked (and they are generally in the 20s). Depending on OOC schedule, we might have one strong opponent each year but generally not even that. This is the major reason I think we should be aiming for 8+ wins every year and think that anything below 7 is a bad year.
I do think Larry can get the offense back on track - if he's willing to make a couple of changes. And hopefully we will commit a little more to defense which would go a long way in strengthening the team. For us it gets down to how we fare against teams like GT, Pitt, UVA, State, Duke and a team like Cal. All these are teams we should be able to beat most years. If we just win these 6 games (and the 2 against weak OOC opponents) we're at 8 wins. I know we won't win all 8 of these every year but we should be capable of winning one of the other 4 most years. And it would help a lot to win the bowl game.
So can Larry do it? I think he can if he truly evaluates what's working and what's not and makes changes to improve the team (and many times this is based on the guys on the team, not just the coaches). But he needs to make the evaluation and changes before the season starts and win game one.
