Would it be considered inappropriate to have a LOR from a collegiate athletics coach? I was the captain of a sports team for a D2 school my senior year and had a really good relationship with my coach. I think it may offer a unique perspective in terms of leadership, teamwork, etc. Along with LORs from professors, research advisors, my employer, and an md, it could help illustrate certain aspects of my character that couldn't be expressed in the other letters. What do you think?
