I have thought about this a lot. I think ultimately the ACC is the more difficult conference. Now that being said of course it fluctuates from year to year and comparing this year in the ACC against the best conference of all time is not apples to apples.
But let's think about it. If you assign a power rating to each school and line up the two conferences from strongest to weakest member, the ACC comes out ahead. I'm not talking about current teams, but overall program strength and the potential of each school.
At the top of the ACC, you have two five-star programs in Duke and Carolina. The Big East had nothing at that level. UConn is the best of the bunch from that league and i'd say they are in the next best category, maybe 4.5 stars. Then you have Syracuse and Louisville which are in both leagues, so that's a wash.
The Big East had Georgetown and Villanova which I think are better than the next group of the ACC. That's what the Big East had - a strong consistent upper-middle tier of which Pitt belonged. The ACC's middle tier is Pitt, UVA, NC State, then you get to Notre Dame (wash) and Wake Forest and Georgia Tech. The Big East mid-tier of Marquette, WVU, and Cincinnati along with Pitt and ND could top that some years.
But the bottom is where the ACC comes out the best, in my opinion. The ACC has Florida St, Miami, Boston College, Clemson, and Virginia Tech. These are all football schools with lots of money. They can compete in recruiting, coaching salaries, travel expenses, the like. They ultimately have much higher upsides as a program that non-football schools from the Big East like Seton Hall, Providence, Depaul, St Johns. And the weak Big East football schools like USF and Rutgers are the bottom of the line.
so I think at the end of the day, the ACC will be more difficult and competitive for Pitt due to the top-quality programs ahead of us, and the much better funded football schools that will normally be below us but are much more likely to be competitive with lots of cash to spend. It's a new world going forward with these TV contracts, and we aren't in the competitive advantage we used to be.
