For starters, Richmond and William & Mary. Both are better academically than BU and Loyola, and both play a game with an oblong ball. Not too mention, they don’t just play football but play it at a high level in the FCS. William and Mary has more prestige than all of the PL already (perhaps service academies notwithstanding). They are the second oldest school in the country to Harvard, they educated several presidents, educated 16 signers of the Declaration of Independence, founded Phi Beta Kappa and had the first honor system in the country. They are a perfect size (6,000) and they have a strong graduate program. And, geographically they fit with natural rivals in American and Navy. Richmond is also strong in academics, with a really good undergrad business program and a decent law school. 4500 students and a natural fit with W&M and the DC schools. They won the FCS championship in football less than 5 years ago, and have a basketball team who has been ranked in the Top 20 in the nation less than 10 years ago.
If you can’t get them, GW makes more sense to me (although they don’t play football). Fordham back in all sports, if they would leave A10 another probably better option.
