Great discussion... If the player has a strong interest in a finance, investment banking, or trading career, Amherst may be the best path. Being planted on the East Coast, Amherst is more proximate to the big finance and investment firms. There is stronger access to top internships within the financial industry.
It does come down to priorities and how important baseball is to the player. If the player wants to play, but they're using baseball to get into a top academic school, chances are, they're ok with a reduced playing schedule and maybe not playing summer college ball. Or, playing summer ball the first few seasons, and then focusing on internships to prepare for their non baseball playing careers.
Pomona has a strong economics program, it just doesn't have the access to Wall Street like Amherst does.
