Agreed fenwaypark. I would stipulate that there are individual players in the Ivy that had both the opportunity and the necessary skill to play in the conferences you mention but made a choice to pursue Ivy athletics instead. However in general terms, I think you are absolutely correct.
When you really take time to think about it, it’s amazing that Ivy athletics are as good as they are given the admissions barriers. It’s a truly special kid that is that talented on the field/court and in the classroom. Congrats to all that have one or more that fit that description in the family.
