Many of the ACC schools are over-baselined. Though I would not think Clemson/Miami/VT need to be worse than a B though.
Wake Forest, Georgia Tech, NC State and Boston College are all A- level, which seems out of wack with the other A- schools:
Georgetown, Louisville, Cincy, Indiana, Wisconsin, Florida, Stanford & Oklahoma. I'd argue that any group of 4 of those 8 are better than Wake/GT/NCState/BC.
Virginia doesn't need to be a B+ and Maryland could be just a regular A- instead of an A as well.
