Since 2004, the ACC has added Virginia Tech, Miami Fla, Boston College, Syracuse, Pittsburgh and Louisville in all sports with Notre Dame as a partial member. Only Tech and Louisville are among the public schools on that list with Pitt being a State related school.
Just for fun, lets say the ACC went on a mission to only take public universities. This means the ACC never added Miami Fla, Boston College, Syracuse or Pittsburgh in ALL sports before 2011-12. That would also mean the ACC would only have had 10 schools (with only the addition of Tech) in 2011-12 before Maryland bolted for the B1G. Assuming Maryland still leaves in 2012, which 5 public schools east of the Mississippi should the ACC have added from the list below to get to 14 members:
Massachusetts, Connecticut, Rutgers, Army, Buffalo, Cincinnati, Akron, Bowling Green State, Kent State, Miami (OH), Ohio, Toledo, Eastern Michigan, Central Michigan, Western Michigan, Ball State, Northern Illinois, Temple, Navy, West Virginia, Marshall, Old Dominion, East Carolina, UNC Charlotte, Appalachian State, Middle Tennessee, Memphis, Louisville, Western Kentucky, Georgia State, Georgia Southern, Troy, South Alabama, Alabama Birmingham, Southern Mississippi, Florida Atlantic, Florida International, South Florida and Central Florida. Note, Pittsburgh is State-related but still considered semi-private and did not make my list.
To me, only UConn, Rutgers, Cincinnati, Louisville and West Virginia seem to make the "big boy" cut. UConn is probably the best one of the group in terms of winning National Titles and being the typical large Land Grant University. Lousiville is the sexy pick these days as they seem to be winning a lot... but will that streak maintain in all other sports not named basketball? Rutgers and Cincinatti are ample but nothing to get excited about. WVU isn't a bad choice athletically IMHO. So are the 5 schools I picked better than Miami, BC, Syracuse, Pitt (and Notre Dame if you really want to count them)?
This assumes the ACC doesn't have the ability to poach the B1G or SEC as well.
