EAGAN, Minn. (AP) — Kwesi Adofo-Mensah spent his first eight years out of Princeton on Wall Street, working as a commodities trader and a portfolio manager. Crossing the country to continue his studies and become an economics professor at Stanford was only the start of a sharp turn on the career path that led him to the NFL. “I was going to wear a tweed jacket and glasses and teach students,” Adofo-Mensah said, “and I still had a lot of decision-making left in me. I wanted to be a part of it in a practical sense.”
