Mendenhall's departure from BYU was primarily influenced by his concerns regarding the sustainability of the university's independent status in college football. He expressed that he had dedicated significant effort and resources to advance the program during its time as an independent, but ultimately felt that he had reached the limits of what could be achieved in that context. Mendenhall believed that the challenges associated with maintaining independence, such as scheduling and competition, were becoming increasingly difficult to navigate. His candid assessment reflects a broader understanding of the evolving landscape of college athletics, where conference affiliations often provide more stability and opportunities for growth. Thus, his decision to leave was not just a personal choice but also a strategic consideration for the future of the program he had worked so hard to develop.
