All 3 are historically pretty strong, and UW is only a few years away from a CFB playoff appearance. All 3 are in key TV markets as well. Any conference that has ND will get TV $$$s. ND would be most powerful in the ACC, and maintaining a semblance of academic integrity would be buoyed by adding those schools. Colorado makes sense too from a TV perspective. Adding one or both of the AZ schools might make sense.
