This is my definition of a "big win". Will Carolina ever get to this level?
We've had a few big wins the past dozen years. I'd count a win against a top 15 opponent as "big."

Obviously we didn't turn any of these wins into championships or even long-term success. It's also kinda sad that these are our only top 15 wins in the past 12 seasons. But we have had some really good/big wins in that timeframe.
If only winning by double digits on the road against #1 counts as a big win for you, then the chances of any program doing that consistently are pretty slim. That's especially true for a program like South Carolina.
