Perhaps the biggest problem I have is our lack of success vs our peers during Dino's tenure; our fellow ACC schools and some of the schools within the conference that we compare closest to.
You can spin schedules, OOC foes, etc all you want, but our performance in-conference has been putrid. Except for our magical year when we were good (and went 6-2 in the ACC), we have not won more than 2 conference games in a season. Those seasons were 2-6,2-6,2-6,1-9 (ND counted as ACC game), and 2-6.
It gets even worse. Except for GT, whom we have only played once, we have a winning record only against VT (2-0). All of these records include the magical season. We are .500 vs BC, Duke and UNC (both of whom we have only played twice). The rest is very grim. 1-5 vs Louisville. 2-4 vs Wake. 1-5 vs Clemson. 1-5 vs NC St. 1-4 vs FSU. 1-5 vs Pitt. Etc.
We have won more than 2 conference games only once in six years. We only have a winning record vs VT (and GT) and we have sucked canal water vs most of the rest.
"But, but, some of those teams were good! Our division of the conference was harder!" Yeah? Here's a cookie and your blanket. Get over it and put on your big boy pants. This is the ACC we are talking about, not the SEC. There is simply no way to spin four 2-6 conference records and one 1-9 in six seasons. I fully admit that Clemson, FSU, and now Miami treat football more like SEC schools do. We should still have a better record than we do against them. As for the rest? No excuse to be a doormat.
To me, that is the thing that needs to change the most. We might need to walk before we can run with regard to the overall record, but we simply have to do better in-conference.
